Dark, Disturbing and Surprisingly Thought-Provoking
I had been eagerly anticipating Mr. Kill ever since its teaser was released during GMMTV 2026: Magic Vibes Maximized. The premise immediately intrigued me, and I was especially excited to see Dew Jisu take on another role after Faceless Love. After watching the entire series, I can confidently say that this was one of GMMTV’s most interesting and ambitious productions.
The story centers on Kaye, a famous manga artist whose dark underground manga Nekros was written under the name “Mr. Kill.” When a series of real murders begins recreating the murders depicted in his manga, Kaye suddenly finds himself under suspicion. Police officer Phat is assigned to investigate and is forced to work with Kaye because nobody understands Nekros better than its creator. From there, the mystery becomes much more complicated as their investigation exposes painful connections to the past and raises questions about whether what they are witnessing is justice, revenge or something far more sinister.
The screenplay by Thitipong Chaisati does a great job balancing the murder mystery, Kaye’s psychological backstory and the developing partnership between Kaye and Phat. Directed by Sakon Tiacharoen, who also directed Leap Day, the series maintains a dark and tense atmosphere while gradually expanding its themes beyond the central mystery.
What I particularly appreciated was how much the series had to say about vigilante justice, morality, corruption, power and the failure of the justice system. It explores what happens when people are failed by the very institutions supposed to protect them, especially those who are poor or powerless. It kept making me question whether taking justice into your own hands automatically makes you as bad as the people you are punishing. If a criminal escapes because the system is corrupt or ineffective, can we really blame someone for wanting to make that person pay?
That dilemma reminded me of Death Note, particularly the question of whether killing criminals can ever be considered justice. Is Thun truly evil if the people he targets are criminals who escaped punishment? Is Kaye weak because he could only express those violent ideas through his manga? Or is there a difference between imagining revenge and actually carrying it out? The series doesn't make these questions easy to answer, which is one of its biggest strengths.
Dew Jisu was excellent as Kaye. He brought so much depth and emotional subtlety to the character, and there were moments when I could understand exactly what Kaye was feeling just by looking at him. Episode 7 was especially impressive. The scene where Kaye talks to his reflection genuinely made me wonder whether he really was the killer. Dew was an excellent fit for this role, and yes, somehow he is still ridiculously handsome even when crying.
Tee Teeradech also did an amazing job as Phat. This being his first main role in a series makes his performance even more impressive. He brought the necessary intensity and seriousness to Phat, while also working extremely well opposite Dew. Their partnership was one of my favourite aspects of the series.
Off Jumpol was another standout. He has always had a talent for portraying those irritating characters you love to hate, so watching him take on a genuine villain felt like a natural progression. Thun's double life as a news anchor and serial killer made the character even more disturbing.
Mr. Kill is not an easy watch. It is dark, emotionally heavy and sometimes genuinely stressful. Around Episode 7, I had to pause the series because I needed to get myself into the right headspace and, honestly, the proper state of grace before continuing. The gruesome imagery also makes this unsuitable for viewers who are particularly sensitive to violence. And if you are coming into this expecting a bromance, don't. This is very much a crime thriller first.
One scene that really stayed with me was Kaye burning Commissioner Chaiwat. It was almost poetic in its brutality and felt like fitting retribution for the role Chaiwat played in the demise of Kaye's father.
I did have a few reservations about the final episode. The one-year time jump confused me because I wasn't entirely sure what it was supposed to signify. If the intention was to show healing and recovery, I am not sure that reopening the relationship with a joke about a lighter was the strongest choice. I also would have liked to see the Uncle actually facing the consequences of his actions in prison. More importantly, I wish the series had shown some form of counselling or support for Phat, Praew and the other people whose lives were devastated by these events. Would that have been completely realistic? Probably not. But I would still have appreciated a little hope.
Despite those criticisms, I really enjoyed the series. The ending itself wasn't particularly surprising, but there was enough misdirection throughout the story to keep me guessing and make me want to wait an entire week for the next episode. The performances were excellent across the board, and Sakon Tiacharoen deserves credit for drawing so much from the cast throughout the series.
Mr. Kill was a dark, emotional and unsettling rollercoaster that asked uncomfortable questions about justice, morality, revenge and the world we live in. It wasn't perfect, particularly in the finale, but it was compelling, well acted and remarkably thoughtful. For me, it is easily one of GMMTV's best series to date.
