*Queen Mantis* (also *The Mantis: Original Sin*) has made an impressive debut, particularly in its ability to combine psychological tension with a gripping mystery. The show follows Jung Yi‑shin, a woman imprisoned for the murder of five men over 20 years ago, and her estranged son, Cha Soo‑yeol, a police detective. When a series of copycat killings emerge, mimicking Yi‑shin's methodical murders, she offers her help in solving the case—but only if Soo‑yeol acts as her direct interlocutor. The dynamic between mother and son is the emotional core of the drama, providing much of the show’s tension and complexity.
One of the standout features of *Queen Mantis* is its strong performances. Go Hyun‑jung delivers a chilling portrayal of Jung Yi‑shin, walking the fine line between cold, calculating villain and a woman haunted by her past. Jang Dong‑yoon’s Cha Soo‑yeol is equally compelling, capturing the internal struggle between loyalty to his mother and his duty as a detective. The chemistry between these two actors drives much of the series’ emotional weight, especially as secrets from the past begin to surface. Their conflict and strained relationship are the real heart of the show, and the two lead performances elevate it to something more than a simple crime procedural.
The pacing of *Queen Mantis* is another strong point, particularly in its ability to maintain a slow-burn tension. Each episode ends with a cliffhanger or revelation that keeps viewers engaged. For example, Episode 3 drops the bombshell that Yi‑shin's first victim was her husband—Soo‑yeol’s father—setting the stage for a deeper exploration of their fractured relationship. The atmosphere also plays a crucial role, with the show’s moody, almost oppressive tone adding to the sense of unease. Cinematography and sound design create a chilling backdrop, making every scene feel layered with suspense.
Ultimately, *Queen Mantis* is a strong contender for fans of psychological thrillers, family dramas, and crime procedurals. If you enjoy stories with dark moral ambiguity, complex family dynamics, and atmospheric tension, this series will likely resonate. On the other hand, if you prefer lighter, more episodic crime dramas or need every plotline to be equally fleshed out, you might find some of the side elements lacking. So far, though, it’s shaping up to be a compelling watch, and it will be interesting to see how the show handles its concluding episodes.

Vigilante Serial Killer
I have not seen the original French version, nor the American spin off so I started this with only the description to go on - an imprisoned serial killer mom who forces her detective son to work with her to solve a series of copycat murders.Go Hyun Jung as The Mantis dominates every scene she’s in owning this serial killer mom role. Early on there’s a Dexter like assertion that her murders were only of really bad men who had escaped the failed justice system. She forms an interesting relationship with the detective who captured her and through whom she negotiated an unusual arrangement for her imprisonment which included provisions to give her son a new identity and to raise him to be like the detective. While The Mantis is cynical about the justice system (hence her vigilante justice) she admires the sincerity and naiveté of the detective. She would prefer her son to grow up molded after the detective than herself.
This show directly brings up the nature/nurture issue. The son fears that his bloodline connection to his serial killer mom will determine his behavior and future. It’s this fear which leads him to often react seemingly irrationally in his interactions with her, and with his wife, and his fears should they have children.
At times the killer mom projects an insane enjoyment of the torture she inflicted on her victims said torture inspired by the form of the torture they themselves inflicted on their own victims.
The plot twists and reveals near the very end cascade rapidly one after another and lead us to an understanding of why she became that way. And I promise that these final reveals will inspire sympathy for her if not acceptance of her actions. Think of Hannibal from the books and movies series and his origins in WWII as a small child struggling to survive the horrors of the German/Soviet front.
The show is a mere eight episodes so pacing is a problem only for the impatient.
The reason I rate it a 9.5 is connected to a few flaws in plotting and certain scenes. There are some clumsy lurches in moving from certain plot points to the next. Second time through these became even more glaring. The story, like a magician’s sleight of hand, glosses over them to move things along. And then in a very few scenes the absurdity just jumps out and no sleight of hand can hide it-e.g. washing machines with windows scene.
Within the larger context of a great story and Go Hyun Jung’s performance these flaws are forgivable.
There’s a final scene which promises a sequel. Such a sequel would have to shift from the backward looking to the present and future, and consequently will be very different, but I welcome the attempt just to see this fascinating character in action again.

A Ruthless Ride Led by a Queen Who Owns Her Darkness
You will always find me seated for a good “women going to town on evil men” drama, and Queen Mantis absolutely delivered. I loved every second of it.Go Hyun-jung was phenomenal with that innocent face and disarming smile, she murdered men in cold blood without a hint of remorse, and somehow you never once felt she was on the wrong side. She was strong, confident, unapologetic and honestly, she didn’t even feel like a murderer, more like a saviour.
Jang Dong-yoon played his role perfectly as the emotionally stunted son who couldn’t see things from his mother’s perspective yet still longed for her love. Watching his growth was one of the most satisfying parts of the show. His gradual realization that life isn’t black and white, and that assailants can also be victims was thoughtfully done.
The show also nailed the suspense around the copycat killer. There were moments I even suspected the male lead! The mystery kept me guessing, and even when I thought I’d figured it out, the reveal still hit hard. That’s a rare win in thriller storytelling.
The supporting cast complemented the mother-son duo without stealing the spotlight, and the story balanced their arcs nicely. The final reveal, with the grandfather turning out to be pure evil, was shocking. I loved that the show didn’t take the “justice will be served through the system” route and instead let the female lead finish him off herself. The setup for Season 2 was the cherry on top.
Of course, it’s not flawless. The logic slipped a few times, the trans villain subplot felt unnecessary, and the pacing dragged a bit toward the middle. Still, those flaws were minor compared to what Queen Mantis got right.
Thoroughly enjoyed it from start to finish. If I dare say, this might just be one of the best dramas of the year.

The Queen of Serial Killer Dramas
Go Hyun Jung is without a doubt, the stand out performance not only in Queen Mantis but for the year. She delivered her role perfectly. As much as it was chilling, the depth she brought to a mother who used brutal methods to despatch terrible men in their own right, who also longed for her son, was unforgettable.Although a remake of the French show, Mantis, I have found QM the best serial killer kdrama to date. The reason: superb acting, very good writing and the reigning in of the classic tropes. The subject matter re QM’s origins is not pleasant but it is handled in a steady manner ie not over the top.
This show looks into the cause of human behaviour both nature and nurture. Its premise is ultimately that nuture is the cause and not someone’s bloodline. The exploration on how people react when a key employer (in this case, the mine) shuts down is a reminder of the tragedy that follows.
Trust is pivotal to each character and storyline. How this I stretched, lost and then regained comes down to the inner strength of each character.
Jang Dong Yoon is very good as the son of Queen Mantis. I liked how this show explored the relationship between Su Yeol and his wife and how, in hand with this, Kim Bo Ra played a very understated performance.
Cho Seong Ha delivers as he always does but I felt that his character was a little bit too wimpy. Also, they should have used a different (younger) actor in the flashbacks.
As for Lee El, a strong performance that was like a second fiddle at times. This role contrasts to her performance at the same time in My Awesome Star where she portrayed the jealous and delusional starlet so well.
When it came down to the big reveal, I wasn’t surprised. The red herrings were top notch. The layers, challenging.
Queen Mantis is eight episodes, the right amount for such a genre. Anything more would have detracted from the quality of the show but it’s clear a sequel is in the works.

Frusterating
I wanted to like this. I find the family dynamics very interesting and the acting by the leads compelling. Unfortunately, the show is hampered by it’s shorter form. The side characters get little screen time so it os hard to care about them. I also found the “twist” of the new killers identity pretty offensive. The show goes out of its way to perpetuate harmful stereotypes by saying that the killer isn’t really trans, they are just mentally ill and transitioned to make it easier to kill. Ick!Was this review helpful to you?
Mother of a Twist!
Jung I Sin is a convicted serial killer known as the Mantis. Twenty years ago, she brutally murdered five men and shocked the nation. Her son, Cha Su Yeol, grew up hating her and everything she stood for. Now he works as a police officer, determined to stand on the opposite side of crime. But when a new murder case surfaces and mirrors the Mantis killings, Su Yeol is forced to seek help from the one person he despises the most. His mother. To catch a copycat, the hunter must team up with the original predator.And that is when the madness begins.
Queen Mantis is the kind of drama that grabs you by the collar and whispers, “Trust no one.” From the very first episode, my brain was in detective mode. Who is Jung I Sin really? Is she truly a monster? Is she protecting her son? Did someone else commit those murders? Was Lee Jung Yeon involved? Every episode added new layers, new flashbacks, new clues. Just when I thought I cracked the case, the drama said plot twist and pulled the rug out from under me. It is twist on twist on twist. A full Inception experience but make it crime thriller.
What makes it addictive is not just the mystery but the emotional undercurrent. Go Hyun Jung as Jung I Sin is simply phenomenal. In the beginning, she carries this eerie, almost supernatural aura. The way she stares, the way she smiles slightly, it feels like she knows ten secrets you do not. I kept asking myself if she was evil or just misunderstood. As the story unfolds, we see what truly drives her. Her son. Suddenly the devil horns start looking suspiciously like angel halos. It becomes a powerful reminder that you can never judge a book by its cover and that everyone has their own scars and silent battles.
The chemistry between Go Hyun Jung and Jang Dong Yoon is chef’s kiss. Their relationship evolves from cold resentment to something painfully tender. You can feel the years of anger, betrayal, and longing in every scene. Watching Cha Su Yeol slowly confront his past and his feelings toward his mother was deeply satisfying. It was not just a crime investigation. It was emotional therapy wrapped in a thriller.
Kim Bo Ra as Lee Jung Yeon, however, left me a little puzzled. She definitely earned a spot on my suspicion board more than once, but beyond that, her impact felt limited. I kept waiting for a bigger narrative purpose. Still, she did her job in keeping me paranoid, so perhaps that was the point all along.
The dynamic between Jung I Sin and Choi Jung Ho also had me tilting my head. Are they allies? Old friends? Is there unresolved tension? Or is it simply detective and convict with complicated history? Their gray area added another intriguing layer to the story, even if it never spelled things out clearly.
What I loved most is how this drama makes you suspicious of almost everyone. No character feels entirely clean. No one feels entirely guilty either. It plays with your moral compass and dares you to decide who deserves redemption.
And that ending. Oh, that ending. Revenge completed. Truth revealed. Justice served. The good people finally smiling. I was genuinely happy that Jung I Sin received her form of peace, especially with her son standing by her side. After all the darkness, it felt earned.
Overall, Queen Mantis is a genius blend of mystery, emotion, and psychological tension. It keeps you hooked, guessing, and emotionally invested until the very last minute. If you are a fan of crime thrillers that mess with your head while quietly breaking your heart, this one is a must watch. Consider yourself warned. Once the Mantis locks in, there is no escaping.

surprisingly good watch
Let me start this review by saying how much I missed female characters who are written as complex by nature, not just because it’s a trend. Another thing worth praising about this series is its storytelling. The narrative doesn’t waver. Instead, it moves confidently from point A to point B. Although the plot is quite dark, I can absolutely see myself rewatching it for that reason alone. Kudos to Go Hyun Jung and Jang Dong Yoon for their excellent performances. They carried the drama by portraying one of the most complex relationship between mother and son I’ve seen on screen so far.Was this review helpful to you?

Good Crime Drama that sometimes suffers due to Lapses in Logic i.e. Lazy Writing.
What an interesting way to start a series with a cop whose mother is an imprisoned serial killer. However, someone is mimicking her kills, which brings mother and son back together after 20 years. There were so many layers that could be explored with this story, and some were. The ML struggling to reconcile the mother he remembered, who was kind and caring, with the monster she became. The monster that is his mother who despite her depravity seems to have true love and care for her son whom she wants to protect.I found myself wanting to root for the mother, but just couldn’t get there because of her depravity in killing what was believed to be “innocent” men. And then there was the question of who was mimicking her kills and why? If the series had really zeroed in on these interesting themes this could’ve been an excellent show.
Unfortunately, the main character doesn’t live in a vacuum. He has a spouse and colleagues. All of whom had some contrived moments to push the story forward. Moments that could’ve easily been written in a way that would’ve organically driven the story rather than having people do incredibly stupid and unrealistic things. Despite these lapses in the storytelling this was a good series. There were some great twists and the acting was good. The way the series ended there is the possibility for another season. If there is a S2, I’d watch if nothing else but to learn what happened to Detective Choi.

This is a good series
This is a good series. I haven't watched the original La Mante (the French version), so my whole opinion is based just on this Korean adaptation.Even though I’ve seen tons of shows and movies in this genre, and there’s not a lot that feels new or original in terms of the story, I still really enjoyed it. The cast is probably the best part of this version. The queen absolutely owns the role—she brings everything to it and really brings this “mantis” character to life. She actually reminds me a bit of Sarah Linden from The Killing, but from a very different angle.
Fans of Mindhunter and The Silence of the Lambs should definitely give Queen Mantis a shot. The queen has a moral compass kind of like Dexter Morgan, but set in a world that feels more like Hannibal Lecter meets Edmund Kemper.
I really hope the son develops into more of a Clarice Starling-type character. But honestly, it’s a bit weird that he seems to be falling in love—feels super out of place given the dark family history. Personally, I don’t think he’s capable of giving or receiving love. But maybe the writers are setting this up for a twisted climax, like the ending of Se7en.

Finally a master piece acting by lead
She carries the show, the ml still a bit new in expressing himself skilfully but his complex bg allows for it. Thought this was kill bok soon continuation when i started and totally forgot to see siwan on screen. The usual abusive hub as premise is forgiven as there should be more to her becoming if not plot rating will drop further. But fl acting… the last time i was blown away by acting alone was kim hee ae in world of married…Was this review helpful to you?
