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.

The ‘Flood’ isn’t “Flooding”
From my opinion, the “Flood” is not just about the rising tide. In this film, the water serves as a metaphor for a vast sea of memories and emotions. It’s a literal and figurative drowning in one’s past. Kim Da-mi nailed her role very well. Hats off!Spoiler ⬇️
The story functions like a system failure—an endless loop that restarts every time the objective isn't met. It’s fascinating to see how the narrative explores the concept of emotional induction. The experiment’s core theme, ‘a mother searching for her lost child,’ is both heartbreaking and chilling. Once the emotional goal is achieved and "Jain" is found, a new "object" is launched, showing the cold, clinical nature of the experimenters behind the scenes. Anna’s intense emotional reaction suggests a deep, genuine bond, but in a world where memories are manipulated, it’s hard to tell where the truth ends and the simulation begins.
At the end, The Great Flood is a haunting sci-fi that forces us to question what makes us human. Is it our biological heart, or is it the inescapable flood of emotions we feel for those we love?

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!

Not what I expected, still good.
For anyone who didn’t read the synopsis and only saw the still cuts, this movie might surprise you.It did for me, but it still good.
The Great Flood starts off like a disaster movie, then kind of shifts into sci-fi. The flood is really just the beginning, and after that the story goes somewhere else. If you’re not paying attention, it’s easy to get a bit lost.
The genre switch won’t work for everyone. It’s confusing at first, but once it settles, the emotional moments hit more in the middle and toward the end.

Interesting movie
Interesting movie that remind me source code by Duncan Jones.It starts like a disaster movie, but at a certain point it turns into something deeper: a science-fiction film about human emotions and what makes us human.
Excellent performance by actress Kim Da-mi, who manages to define and portray her character very effectively.

the concept of replacing humanity with IA
at first i did think it was gonna be a natural disaster type movie but man i thought the plot twist was gonna be good, instead all i got was an underwhelming feeling seeing it as propaganda for the low birth rate, not only in South Korea but also the rest of the world; the irony of it being a child made with artificial intelligence, i'm afraid this didn't awake some maternal instinct but that's just me i guess.With the use of IA on the rise i'm afraid there won't be enough water to flood us all to extinction. I can see the irony of using IA to replace humanity but the water flooding being the main plot feels like a joke that didn't land.

Tsunami (The Great Flood) is not the Main Role in a Disaster movie, huh !? :O
**** SPOILER : THIS IS A RANTING REVIEW ****I love Disaster/Survival movies.
So I was all excited n waited for this movie, seeing in Netflix "Coming Soon" but I'm highly disappointed now!!
Promoted as a Disaster movie n so expected a Full Length Disaster Survival movie but NO!
The Title, Cover pic n Summary cheated me :(
(So the Tsunami is not the main role but it's just a support role / a minor side role, Instead AI project is the main lead here, haha).
***
After watching first 20 mins, where there are Good CGI scenes of Flood and the struggle and when there is mention of some AI baby project, AI emotions builder project etc and there's a Time Loop -- I'm all excited thinking that I'm getting a combo of Disaster + Sci-Fi.
But NO!
IT IS EXCLUSIVELY A SCI-FI / TIME LOOP PLOT, WHICH IS NOT THAT CAPTIVATING.
Even Hae Soo Oppa's character didn't capture my interest (I like to watch his dramas).
***
A Full Length Sci-Fi movie with Disaster theme as subplot but promoted as an exclusive Disaster movie, actually gave a great disappointment to disaster movie fans (like me, who love disaster/survival more than Sci-Fi) and ruined the interest to watch the Sci-Fi plot.
(Just a thought -- Since AI is the new trending talk of the town, now-a-days, maybe the movie team wanted to be one of the first ones to grab a place in that buzz, with their movie on that theme but left with many disappointed audience and bad reviews).
*** THE PLOT :
The Sci-Fi Plot is Good
but somehow Everything (Acting, Direction, Execution) gone Messy.
This Plot can be executed better n with more clarity.
The Time loop or iterations, which are actually inputs to the AI project mentioned in the story -- These sound interesting but NO, it got confusing n uninteresting at one point.
Just the CGI scenes are Good -- loved them.
*** SOME MORE RANTING:
The Title should be
"The Baby project" or
"Finding the Kid" or
"The Emotions project" or
"The Time loop"
Only then, Disaster movie fans, like me, will not be misled!
Aigoo, me! :(
The disappointment is so great that I wrote this lengthy RANTING REVIEW, which I never did even to a very bad movie/drama :o
*** RATING:
My Rating is 6.5 / 10
My Final take on this movie:
If U are an exclusive disaster/survival movie fan n strictly not Sci-Fi, then this is not for U.
But if U are a fan of Sci-Fi/Time loop movies too, then U can give a try!
But watch with zero expectations!!

Left Me Confused And Annoyed
I have been waiting for this movie and didn't expect it to be disappointing. Usually disaster movies are quite entertaining even if they are run of the mill stories but trying to create a twist to the story ended up backfiring for the writer/director.The initial plot revolves around a mother waking up to discover massive flooding around their apartment complex. The water is rising at great speeds and she starts to rush her young son to get them out of the house. The son, like a typical child, doesn't comprehend the danger and adds to the mother's anxiety and the audience's annoyance levels. This whole section is quite good. The mother doing her best in order to survive and finds help from man who is sent to extract her to safety for her research.
HEAVY SPOILERS IN ORDER TO EXPLAIN MY DISLIKE
The problem with the plot starts when they finally reveal that the child is AI and created to develop emotions into an AI as the future of humans (bizarre).
Once the mother gets to the roof, the team not only shoots the man who helped her (important) but also remove a chip from the child's head that holds it's memories/data. They then show a series of rockets jetting off into space just as floods are coming in. This is odd since every place has already been flooded so where are they lifting off from? Not explained. While in space, the rocket carrying the mother is damaged and she is injured from the debris so she also extracts her memories and transfers herself into an AI mother. They then replay the scenes of the flood with slight variations each times. In most scenarios the son is missing and she has to find him and the scenarios keep repeating which is not depicted well.
Some charcaters retain their memory like the man remembered getting shot and works against the extraction team. However, the man is not real but in this game like setting or training runs should be an NPC. There are few more characters like this. So haven't they already achieved AI with human emotions?
The end goal appears to be to return to Earth with AI. With human emotions. What about saving actual humans? What are other countries doing? Is every country sending rockets with AI? No millionaires and billionaires fighting to get a seat? All rockets look the same, no other country designed a different rocket with a different mission?
SPOILERS OVER
There are too many plot holes, too many things happening that you don't quite understand and it made me womder what I watched when it was finally over. I had to read other comments to fill in some gaps and the more I read, the worse this movie became.
The movie doesn't really deserve even a 6 but have to give them points for effort for the VFX and the setting. It did keep me interested even though I was lost at the end. The plot was just too ridiculous which feels like they didn't develop the story well or ask questions like WHY and just gave it their all on the special effects aspect.

The worst time wasting and boring movie I've watched in 2025
This is clickbait and worst netflix original I've watched in a very long time. The kid is probably the worst annoying character in the whole omniverse, petaverse, universe.. I'm not even bragging when I'm saying that but this movie is just the worse. If you are a survival lover it's never worth watching. Sci fi lovers are saying 2nd part is confusing and they like it but trust me it's not confusing, it's just annoying, super predictable and boring, like you can 100% predict the story and the story is boring, repetative and slow paced. I've never felt such annoyed by any movie yet in my life I swear.If you don't believe me, watch and you'd know and if you do believe me, It's never worth watching and I hate it the most.

Anyone else found the son annoying.
The child was very annoying It's like he did not understand the world around him. You have water on the ground in your apartment and you want to swim in it. The first thing you do when you wake up in the morning is wanting the swim? The folks in the apartment block or trying to survive and... he wants his mother to carry him? No! and the Mother, is a super "Mary Sue". plot armory protected her until the end. No healthy man can watch this nonsense. Do not waste your time with this feminist dribble. Netflix Execs had their hands all over this production. Please Korean for the love that all is Holy, do not take cues from America regarding modern day entertainment. There is a reason why Hollywood is broken today in 2025 and is in freefall.Was this review helpful to you?

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.

So whats the point?
I watched this movie completely blind without even seeing the trailer and thought i was getting the average korean disaster apocalypse film but truly i was blown away by the sci fi AI combo, Literally why??? why didn't they just make it a regular disaster film why are we dealing with artificial intelligence reincarnation and robots all wrapped in the disguise of an Disaster movie highly uncessary in my opinion but too each their own this was however not my cup of tea in the slightestWas this review helpful to you?
