Incase if you can’t get this movie this might be helpful!
At first, The Great Flood may not feel like a “bad” movie, but it can definitely feel confusing, especially if you’re used to traditional K-drama or Korean films with a clear emotional or linear storyline. This movie suddenly shifts tone and narrative, which can be disorienting. However, once you understand what the film is actually about, it becomes deeply meaningful and emotionally powerful.The world in the movie is already ending. Humanity is almost extinct. The experiment exists because humans are trying to recreate humanity, not just biologically, but emotionally. They realize that without real emotions, especially love, the new humanity they create will never truly be human.
This is where An-na and Ja-in come in.
An-na is part of the Emotion Engine Experiment. She agrees to have her brain implanted into a simulation where she relives the same scenario again and again which is loop as y’all know.
Her role is to demonstrate genuine human emotion, particularly maternal love, because nothing is more raw or instinctive than a mother’s love for a child.
Ja-in, the child, is technically “just a subject.” She is supposed to abandon him. She is meant to choose logic over emotion. But she doesn’t. She loves him like a real child — and that is the entire point of the experiment.
An-na is tested to see if she can:
• Form real emotional attachment
• Make moral choices
• Choose love even when logic and rules tell her not to
She fails thousands of times.
The drawings scattered throughout the movie are not random. They represent past loops of the simulation. Each drawing shows Ja-in remembering her words: “I’ll be back. Wait for me.”
That’s why he keeps hiding in the closet every time. That’s why he keeps drawing the helicopter scene — and why the drawings slowly get better and more detailed. He remembers. He learns. He feels.
When An-na once tells him, “Draw me with some color,” the drawings begin to change. This proves emotional memory exists — even inside a simulation.
Her shirt changing numbers shows how many times she has repeated the loop. Each number represents another failure. Another reset. In total, she is trapped for 13,499 attempts, spanning around five years from her perspective (or even longer depending on interpretation). Some theories place it closer to 21,499 days, roughly 58 years, emphasizing the unimaginable emotional weight of the experiment.
The AI systems try to stop her ( mans with gun’s) They want to reset the simulation because the machine only activates when the subject reaches their version of emotional perfection. The world ends over and over because the simulation can run thousands of apocalyptic scenarios faster than real time.
The truth is:
An-na and Ja-in are already dead.
This is a machine using their memories to learn how human emotions work so it can create the next generation of “humans.”
In the end, An-na passes the test because she chooses love over logic.
Ja-in separating from her shows free will — something artificial intelligence cannot fake. When she is allowed to return to Earth, we see others who have also passed similar simulations. Humanity doesn’t survive because bodies are recreated — it survives because love was successfully learned.
The final message of the movie is clear:
Being human isn’t about being real or artificial.
It’s about love, memory, sacrifice, and the choices we make.
This movie isn’t confusing — it’s layered.
And once you understand it, it’s devastatingly beautiful. Also including few extra words I would say the experiment proves humans are defined not by survival instincts, but by who they choose to save, plus many of people have asked why “love” they would better come with something else but going deep down maternal love is used because it’s the hardest emotion to fake or replicate while AI can simulate logic endlessly, but love requires irrational sacrifice…
That’s it!!

The Great Flood: An Average Sci-Fi Wrapped in a Disaster Movie Title
I really thought it would be a full-on disaster thriller like Flu, Tidal Wave, or The Tower—raw panic, survival instincts, and humans fighting nature at its worst.
Instead, the movie slowly drifts away from the idea of a flood disaster and dives into AI, modern science, world destruction, and a futuristic concept of human evolution.
The title promises one thing, but the story delivers something completely different. The “flood” feels more like a background excuse than the core of the narrative. The sudden shift toward sci-fi philosophy and AI with an emotional engine feels forced and confusing rather than thrilling.
I wouldn’t say the movie is bad, but it definitely fails to meet expectations set by its title and promotion. The pacing is uneven, the emotional connect is weak, and the sci-fi ideas are not explored deeply enough to feel impactful.
For me, it’s a one-time watch—an average sci-fi film with nothing truly memorable.
I went in excited, expecting edge-of-the-seat survival drama, but walked out feeling slightly fooled by the title 😂.

An episode feeler!
Don’t worry, even if you do not watch it, you are not missing out on anything grand!🥺, it is enough to watch as an episode feeler. If you are patient enough the storyline is okayish to keep you watching till the end but not great enough to rewatch!I found the editing a bit awkward at some points. It felt as if some scenes were cut probably leading to absence of smooth transitions but you can look past these if you are more interested in the plot.
I would recommend this movie if you are up for something light. Do not watch this if you are up for a deep/ intense or nerve wracking type of natural disaster plot! Moreover, the flood and how deeply it impacted everything as a natural disaster was not the intense type. I mean you wouldn’t say, “ Wow, indeed that was the great flood” after watching the drama!😂😭It felt so dry therefore you may easily feel bored or triggered to drop it.
At some point we do get the message they wanted to convey but it ended up as a miss.😭
However, Dami and Park Hae-soo nailed their roles and that can’t be overlooked!

A Good Idea That Comes Out Messy
I actually liked this film. The acting and concepts are really good and set up an interesting plot, especially when Hee-jo begins to tell us humans are just cruel, so An-na should be too. But once the whole space thing begins and An-na repeatedly goes through the same thing over and over, the suspense wears off. I understand what they were trying to go for, but there’s too much happening at once to grasp it in a natural way. Overall, a decent film that I wasn’t bored by, but unlikely to watch again.Was this review helpful to you?

AI propaganda
Honestly, it's pure AI propaganda. The idea of humanity being replaced by AI is just another way of showing us what the future holds.I thought it would be a beautiful survival story, or I wouldn't even have cared if it were a sad story.
However, I must congratulate them on the acting and the casting choices. It was one of the highlights of the film.
The irony is that we are rapidly heading towards the extinction of the human race thanks to the use of artificial intelligence!!!
Lets see ig.

Not just a flood — a story of love, sacrifice, and what it means to be human
The Great Flood is not just a disaster or sci-fi movie - it’s a layered story about emotions, memory, and what it truly means to be human.The story begins with JaIn, an AI (Al) who is created, not as a weapon or machine, but as something meant to learn and feel. Anna later adopts JaIn, and what follows is not just a relationship between a human and an AI, but one between a mother and a child. Their bond becomes the emotional core of the entire film.
Then the Great Flood happens ^ a catastrophic event that changes everything...
Amid the chaos, Anna and JaIn are captured, and from here the story takes a much deeper turn. Anna is sent into space, where she is ultimately hit by a meteor. But her death is not the end.
Before dying, Anna transfers her memories into the Emotion Engine, and this is where the movie truly becomes powerful. What we see next is a "time loop " the world repeats itself again and again, almost like a video game restarting from the beginning....
Why does it repeat?
Because JaIn needs to learn.
Each loop exists so that the AI can understand human emotions ,,love, fear, sacrifice, pain, attachment. If JaIin fails to understand, the world resets, and everything begins again. The repetition isn’t a flaw in the story — it is the story.
Anna dies.
The world resets.
Again and again.
Until JaIn finally begins to understand what it truly means to feel.
That’s when the meaning becomes clear.....
Part 1 is reality....
Part 2 is memory .... 'stored inside the AI'....
Everything that happens afterward is not just survival, but learning....Learning love. Learning loss. Learning what it means to be human.
And this is why The Great Flood hits so hard emotionally.
And DaMi delivers an incredibly powerful performance. She doesn’t need dramatic dialogues ,her eyes alone carry fear, warmth, pain, and love. She makes Anna feel real, and her bond with Ja-in feels genuine and heartbreaking.
By the end, this film stays with you , not because of destruction or visuals, but because of its emotional depth and its message.
"The Great Flood isn’t about the end of the world. It’s about an AI learning how to have a heart"

heads up not a disaster movie...
The title of the movie can be quite misleading cause I thought it was a survival disaster movie. However, suddenly they start introducing the sci-fi elements which just throws it off pace....my focus was on the flood but now the story is completely different and the flood becomes redundant.*Spoilers ahead*
Basically the story is in a way showing what AI deep learning/training looks like. The FL is training AI children to make an emotional connection through the repeated trainings. This is what the company believes will save mankind. Just as how she needs to make a child she also needs to make a mother. The training scenario given to the mother was finding her lost child in the middle of the flood. How the AI trains is situational training basically (something like supervised learning). So they made this concept into a movie.
Hence the process of finding her son in the flood just loops and loops with different scenarios until they finally succeed.
The story was not strong enough for me to find any emotional bond with the characters. So this might not be everyone's cup of tea!

Promising 1st act, followed by terrible 2nd and final act
Starring Kim Da Mi, The Great Flood is more than just a disaster movie, and you won't realize it unless you actually give it a try. The outcome, for me, was a big disappointment.The opening 30 minutes is breathtaking, it is the movie's strongest point. It is a "breathlessly tense" survival thriller with impressive digital effects that capture the terrifying scale of a global tsunami.
The protoganist, An-na (Kim Da-mi), a top-tier Al researcher performance is also greatly appreciated. Her maternal role performance is praiseworthy. She carries the physical and emotional weight of the movie, making her desperate fight to save her son feel grounded and believable.
The biggest problem and the twist comes in the second half, where the movie pivots from a simple disaster flick into an "ambitious action-packed puzzle box". Drawing comparisons to films like Edge of Tomorrow and Interstellar, it explores a recursive, "time-looping" narrative. However, this tonal shift leads to a super complex plot with so many loopholes, that by the final act I already got tired of seeing it till the end, and yes it still disappoints.
My thought - The Great Flood is presented as a disaster movie, however the narrative moves deeper with high ambitions, and a very little payoff.
My Rating : 3.5/10

The great flood
I think a lot of people misunderstood The Great Flood because they watched it as a disaster movie. This isn’t a movie about a flood. The flood is just the setting where everything collapses.At the beginning, we learn that An-na is an AI researcher working with the government. Years before the disaster, the government already knew an asteroid was coming. They didn’t tell the public. Instead, they pushed for a project meant to preserve humanity.
An-na’s experiment was a child.
She created him artificially and raised him as her own son. Not as a lab subject but as a real child. She fed him, protected him, and loved him. She wanted to perfect the child first. The government wanted her to create the mother next.
When the flood begins, the authorities come for the child and for An-na who is a researcher. The child is left behind.
Before An-na leaves, she tells the child to hide and wait for her on the terrace. That moment is devastating, because she believes she’ll come back. And he believes her.
She doesn’t. she can recreate the child the way she did before.
An-na goes to space as part of the final survival mission, but her vessel is struck by the asteroid. She’s dying. And in that moment, she chooses to become the experiment too.
She decides to enter the system as a mother.
That’s when the loop begins.
The flooding apartment, the repeating scenes, the desperation none of it is random. It’s an emotional simulation. An AI trying to develop something that can’t be programmed. A mother’s grief and a child’s longing.
An-na keeps reliving the search for her son. The child keeps waiting, hoping she’ll find him. Both of them are reaching for each other across iterations, across failure. The system resets every time emotion falls short.
What makes it painful is that they *are* trying. Together. On opposite sides of the experiment.
In the end, the experiment succeeds not because they survive the flood, but because they finally find each other inside the simulation when reality denied them that chance. The new humans born from this project aren’t just intelligent. They carry memory, attachment, and loss.
That’s the real ending.
Reunion.
The tragedy of the movie is that they couldn’t stay together in real life. The beauty is that they did somewhere else.
People wanted a disaster movie. What they got was a story about a mother who loved her child so much and just wanted to reach him again.
And honestly? That’s why the movie stays with you.

Came for Kim Dami, stayed for the plot
I love how they utilized the sci-fi so well to enhance the drama. It might get boring if you dislike repetitiveness though I can argue it's an important part of the plot that made you empathize with the character and understand the story betterIf you loved Netflix's Wonderland (2024), you would love The Great Flood. This was even better than Wonderland because Kim Dami carried the whole movie's emotional aspect by herself. Definitely a must watch if you love Kim Dami, sci-fi, AND family drama!

When Disaster Thrills Drown in Ambition
Positives:• Intensely gripping first act with high-stakes survival sequences
• Kim Da-mi’s powerhouse performance anchors the emotional heart
• Convincing and affecting mother-child dynamic
• Visually striking and physically immersive set-pieces
Negatives:
• Sci-fi shift in the second half overwhelms narrative clarity
• Repetitive dialogue and uneven pacing
• Hee-jo is underdeveloped and largely functional
• Later VFX, editing, and score sometimes fail to support ambition
• Ambitious ideas clash with the grounded survival story
IN DETAIL [SPOILERS!]:
I like to believe that world-ending natural disasters belong to movies, not to the actual future waiting outside my window. The Great Flood leans into that fantasy, imagining a planet surrendering to water, while narrowing its focus to one woman, her child, and an apartment building in Seoul that is slowly becoming a coffin.
The story begins with Koo An-na and her young son, Ja-in, waking up to an emergency already in motion. The water is rising. The building is filling. Neighbors are panicking, climbing, disappearing. What struck me early on was how quickly the film establishes its physical stakes. This is not about spectacle at first; it is about movement, breath, space, and the constant calculation of how long you can stay alive in a place that no longer wants you there.
That early stretch works. It works largely because Kim Da-mi commits to the role without cushioning it. Her An-na is not stylized or heroic; she is tired, alert, and governed by instinct. The relationship with her son feels grounded, not designed to manufacture tears. Even when the child is difficult, as children in crisis tend to be, the dynamic holds, and I stayed with them.
The film also understands, briefly, how to use the body as a storytelling tool. The best moments rely on physical effort rather than explanation. Climbing, holding, waiting, misjudging distance... these sequences are tightly constructed and genuinely tense. For a while, I was convinced the film knew exactly what it was doing.
Then the writing starts talking too much.
Details about An-na’s past are dropped in with little grace, as if the film does not trust its own disaster to be meaningful enough on its own. Trauma is underlined instead of allowed to exist. Dialogue begins to circle the same ideas. Scenes repeat their emotional purpose without advancing anything. I caught myself drifting, and once that happened, it was hard to fully return.
By the middle of the film, I realized I had lost track of why certain things mattered. An-na’s professional importance, supposedly the reason Son Hee-jo is searching for her, had faded into the background. Hee-jo himself never solidified into a person for me; he remains more of a function than a character, present because the plot requires him to be.
When the film shifts into overt science fiction in its final act, I felt it slip through my fingers entirely. The intimacy that carried the opening is discarded in favor of ideas that are gestured at but never properly shaped. Concepts replace people. Explanations replace tension. Whatever the film is trying to argue about humanity’s future becomes increasingly difficult to pin down.
Worse, the craft begins to unravel alongside the story. The visual effects lose credibility, the flashbacks feel clumsily assembled, and the music presses itself into scenes without offering any insight. Instead of building toward something, the film becomes louder, busier, and less coherent.
By the end, I wasn’t frustrated so much as disappointed. The Great Flood starts with a clear sense of purpose and a strong emotional anchor, then gradually abandons both. Kim Da-mi gives it everything she has, and for a while, that is enough. Eventually, though, the film drowns its own strengths, leaving behind the sense of a story that never decided what it wanted to be.

I wished this movie was actually about a great flood....
I don't really know what this movie was trying to do. It just feels like a movie trying to promote AI or something, and they were developing AI by putting them in the most unrealistic situations? Idk man I just found it all stupid. I know they were also trying to be touching with the "mother and child" thing but all I felt was that I'm annoyed and confused, I don't know what they were trying to do with that. I went into this movie without actually watching trailers or reading the synopsis so I expected that it will be about a natural disaster but nah, they suddenly threw in this AI crap or whatnot.Conclusion: I hate AI and kids.
