A Killer Paradox, Netflix‘s first big K-drama release of 2024, starts with the kind of annoying interaction that anyone who’s ever worked in customer service can relate to. 

What should have been a quiet night shift at a local corner shop turns into an actual nightmare when a rude old man starts making ridiculous demands of Lee Tang (Choi Woo-shik), a regular uni student who’s just trying to get by.

Thankfully, a colleague shows up to defuse the situation, except a new argument then erupts between him and Lee after the old man’s gone home. It’s during the heat of this exchange that Lee suddenly loses it and hits him in the head with a hammer. 

OK, maybe not everyone who’s ever worked in customer service can relate, but you can see where we’re coming from. 

Wracked with guilt over the man’s death, Lee considers turning himself in and even taking his own life until a news report reveals that his victim was actually a dangerous serial killer who arguably deserved everything he got. 

That’s just the start of it, though. A witness shows up, demanding money or she’ll go to the police, which is far from ideal because a relentless detective named Jang Nan-gam is on the case, and he has no plans to let this go until the person behind the murder is brought to justice. 

So begins a cat-and-mouse chase between Lee and Jang that takes you to some truly wild places that you’d genuinely never expect — that is, unless you’ve read the award-winning Naver webtoon the show is based on.

To bring Kkomabi’s darkly comic story to life, Netflix enlisted screenwriter Kim Da-min and director Lee Chang-Hee, a filmmaker best known for a movie named The Vanished, and an equally intense series called Hell is Other People.

Those projects are in good company with A Killer Paradox, which goes to some pretty dark places, too, as the body count begins to rack up. 

Bloody, gory moments are interspersed throughout in a realistic manner, yet it’s the more surreal, dream-like scenes that will chill viewers most.

Chang-Hee makes creative use of Lee’s nightmares and hallucinations, alternating between disturbing imagery and sunny, well-lit daytime scenarios that reimagine each murder from our so-called hero’s perspective.

These sequences in particular really stand out in a genre that’s overcrowded with plenty of far less imaginative takes on murder, especially from a visual standpoint.

Narratively speaking, A Killer Paradox plays with genre, too, by shifting into another beast entirely at the halfway mark, four episodes in.

To say much more here would be to spoil quite how unhinged this show becomes, but just know that Lee’s initial guilt over these seemingly random murders transforms into something else entirely, bringing elements of noir, comedy and even fantasy into what starts off as just a (somewhat unconventional) psychological thriller.

Twists like this live or die on the cast’s ability to keep up and make us believe in the ride they’ve been asked to take us on. Thankfully, Woo-shik excels in the starring role of Lee, who’s just as convincing as a student slacker as he is a tortured hero or hardened vigilante, no matter where Da-min’s script takes him.

Following parts in Train to Busan, Okja and the Oscar-winning Parasite, A Killer Paradox will further cement Woo-shik’s international career beyond his native Korean borders. 

Lee’s nemesis, Detective Nan-gam, is played by Son Suk-ku, who viewers might recognise from Netflix’s Sense8, DP and Designated Survivor: 60 Days. His character is haunted by death as well, but in a very different way to Lee, and his charm plays well on the mirrored cat-and-mouse dynamic that serial killer stories like this love to channel.
