10 Must-Watch K-Dramas For Every Horror Fan

Horror may be one of the rarest K-drama sub-genres, but that doesn’t mean there aren’t plenty of terrifying titles. With each year, Korean television series seem to grow exponentially more popular, which in turn earns greater investment from major streaming services like Netflix, Apple TV, and Disney+. Given that there are hordes of K-dramas designed to be binged, it makes sense that the genre has expanded to new niches, hoping to attract different demographics. From classic romantic comedies to high-octane action flicks to spellbinding fantasies, there is undoubtedly a K-drama for everybody— including those who appreciate a good horror story.

Of course, there is still a world of difference between Korean horror and what most viewers are accustomed to. Admittedly, some of the scariest titles are K-drama thrillers rather than full-blown horrors, but there are countless hair-raising plots hidden in unsuspecting series. While you’d still be hard-pressed to find a gory slasher like Friday the 13th or A Nightmare on Elm Street, there are many petrifying K-dramas that incorporate all kinds of familiar tropes, cultivating a small but mighty sub-genre that is sure to satisfy even the staunchest horror lover.

Death’s Game

One Man’s Untimely Death Leads To A Punishing Cycle Of Reincarnation

Most K-dramas in the streaming age are either upbeat rom-coms or austere period pieces, but Death’s Game is an uncomfortable watch from start to finish. The thriller follows Choi Yee-jae (Seo In-guk), a man traumatized after witnessing a stranger’s death. Following nearly a decade of failed job interviews and no prospects, Yee-jae attempts to take his own life— only for Death herself (Park So-dam) to intervene.

In the hopes of teaching Yee-jae a lesson about the true value of life, Death traps him in a cycle of reincarnation under one condition: he’ll have 12 opportunities to survive in a new body, lest he be sent to Hell. What follows is a tense race against a cosmic clock as Yee-jae begins unraveling multiple overlapping mysteries, all the while slowly regaining his will to live. Death’s Game is a tense minefield of twists, turns, and tragic bouts of irony, and it’s a must-watch for any fan of psychological horror.

Gyeongseong Creature

A Fantastic Fusion Of Zombie Horror & Korea’s Real History

Inspired by the real-life war crimes of research facility Unit 731, Gyeongseong Creature takes a dark chapter of Korean history and turns it into a blood-curdling zombie story. At the heart of the drama are two characters— Park Seo-joon’s Jang Tae-sang and Han So-hee’s Yoon Chae-ok— who band together to explore the strange Ongseong Hospital. The ghastly truth within the building, however, is far worse than either could have foreseen.

As a result of rampant unethical human experimentation, the workers at Ongseong Hospital inadvertently created a nearly indestructible virus that renders its host into a violent monster. Yet, Gyeongseong Creature breaks the rules of zombie horror by giving its eponymous parasitic “creatures” a genuinely sympathetic foundation, along with some unique abilities that stretch the two-season story from 1945 to the 2020s.

Beyond Evil

Two Detectives Attempt To Catch A Serial Killer By Any Means Necessary

Many of the best horror series take something familiar and even comforting to the viewer and turn it into something gruesome and entirely new. Such is the case with Beyond Evil, which starts out as a typical K-drama set in a small town before devolving into the paranoid hunt for a local serial killer.

Detectives Lee Dong-sik (Shin Ha-kyun) and Han Joo-won (Yeo Jin-goo) immediately get off on the wrong foot, with Joo-won even suspecting Dong-sik of murdering his own sister. Nevertheless, as they soon realize, there is nobody else the pair can trust besides each other. The investigation spirals, with anyone and everyone becoming a viable suspect at some point. When the real culprit of Beyond Evil is uncovered, however, even the biggest true crime fans will be gobsmacked.

Hyper Knife

After Falling From Grace, A Promising Surgeon Abandons Her Code Of Ethics

Undeniably, K-dramas tend to be much less graphic than most blockbuster horror movies, but some titles push the envelope with their spine-chilling special effects. Case in point: Hyper Knife, the gripping tale of a disgraced young neurosurgeon (Park Eun-bin’s Jung Se-ok) who turns to illegal operations to continue her career. As Se-ok’s raw ambition begins to eclipse her sense of morality, only Choi Deok-hee (Sul Kyung-gu), her former mentor, can stop her.​​​​​​​

Hyper Knife has one of the most complex female leads in K-drama history, confronting the audience with an ethical dilemma every time she appears on-screen. Not every sequence is easy to stomach, but even the bloodiest surgery serves a clear— and clearly convoluted— purpose, making Hyper Knife both visually and philosophically unnerving.

The Guest

A Psychic, A Priest, & A Detective Team Up To Battle A Supernatural Spirit

Beyond being one of the best supernatural K-dramas of the 21st century, The Guest is also cemented in bona fide horror. Priest Choi Yoon (Kim Jae-wook) dedicated his life to theology in hopes that he’d one day be able to save his possessed older brother, who went on a murderous rampage before disappearing, claiming the life of detective Kang Gil-young’s (Jung Eun-chae) mother. Additionally, prior to the killings, the same evil spirit wreaked havoc on psychic Yoon Hwa-pyung (Kim Dong-wook) and his family, resulting in the deaths of his mother and grandmother.

The three characters, bonded by trauma but nevertheless at odds, are forced to become reluctant allies in their quest for justice. While Gil-young is a certified skeptic who denies the very existence of demonic spirits, Yoon and Hwa-pyung team up to free the world from evil, one exorcism at a time. The Guest oscillates between high-octane action scenes and devastating emotional outbursts, but it ironically feels perfectly balanced, especially for a religious horror story.

Strangers from Hell

When struggling writer Yoon Jong-woo (Yim Si-wan) earns a promising internship, he’s forced to relocate closer to the company. With little disposable income to his name, the young man stumbles across Eden Dormitory, a complex where he is able to rent a suspiciously cheap room. As soon as he moves in, Jong-woo finds himself surrounded by odd neighbors, including a dentist named Seo Moon-jo (Lee Dong-wook).​​​​​​​

Strangers from Hell is a fairly slow-burning horror series despite its mere 10-episode run, as the danger of Eden makes itself known incrementally, creeping up on the viewer with each passing episode. The ensemble cast, eerie scenery, and unsettling cinematography all make for an incredibly immersive story, while the K-drama’s disturbing villain would be right at home alongside Halloween‘s Michael Myers or Saw‘s John Kramer.

All of Us Are Dead

A Group Of Teens Is Trapped At School After A Zombie Outbreak

From Parasyte: The Grey to Train to Busan, Korean filmmakers know how to tell a captivating zombie story. Regardless, Netflix’s All of Us Are Dead stands in a league of its own. The coming-of-age horror series employs traditional genre clichés within its zombie outbreak, but the overall effect still feels visionary and new. Be it the claustrophobic setting of a high school overrun by violent creatures or the heartbreaking group of teen protagonists fighting to survive, All of Us Are Dead feels like a breath of fresh air for the zombie genre.

All of Us Are Dead’s highly-anticipated season 2 will only be an improvement, as it will broaden its scope to explore the aftermath of the initial apocalypse. As such, now is the perfect time to binge the first season, and the 12-episode binge is well worth the watch for anyone who loved The Walking Dead, The Last of Us, or any other iteration of zombie horror.

Save Me

A Politician’s Son Must Infiltrate A Dangerous Cult

Whether you prefer a creature feature or a bloody murder mystery, there’s something to be said about the horror of humanity itself. Save Me isn’t flashy, nor does it have an instantly nightmare-inducing antagonist, but the underrated K-drama nonetheless perturbs the viewer and permanently sears itself into the audience’s memory.

Rather than a vengeful ghost or crazed killer, Save Me spotlights an unassuming religious group known as Goseonwon, dissecting the dangers of cult mentality vis-à-vis Im Sang-mi’s (Seo Yea-ji) desperate journey to escape. There’s more than enough gratuitous violence, death, and dramatic brainwashing to keep the viewer’s interest, but Save Me packs a much deeper punch when you look beneath the surface and face the unrivaled horror of human corruption.

Mouse

A Seasoned Detective & His Rookie Partner Tackle A Deeply Disturbing String Of Murders

That said, most horror fans can appreciate the simplicity of a fearsome killer— something Mouse expertly capitalizes on. The crime drama begins by setting the stage in painstaking detail, to the point where the main cast isn’t introduced until the third episode. From there, the gears shift to follow Detective Ko Moo-chi (Lee Hee-joon) and Jeong Ba-reum (Lee Seung-gi) as they investigate a particularly troubling serial killer case.

Without question, Mouse is the kind of K-drama you can only watch once for a multitude of reasons. On one hand, there are unforgettable twists that recontextualize the entire viewing experience, but there are also over a dozen grisly murders that will linger in the viewer’s mind long after the credits roll. Mouse isn’t the best show to watch after dark, but your bravery will absolutely be rewarded.

Revenant

An Expert In Korean Folklore Crosses Paths With A Seemingly Possessed Young Woman

When it comes to the realm of K-dramas that are actually scary, Revenant is at the top of the list. The enthralling mystery seamlessly blends Korean folklore with classic horror elements, volleying a simple possession storyline into a wildly original thriller. After Gu San-yeong (Kim Tae-ri) is implicated in a string of so-called suicides, a professor with spirit sight named Yeom Hae-sang (Oh Jung-se) comes to her aid.

Revenant is far more than a typical ghost story, but it never veers too far off course to where the audience feels unmoored. With the suspense of The Conjuring, the religious terror of The Exorcist, and a healthy dose of shamanism, Revenant is arguably the best Korean horror series of the decade thus far. Nevertheless, the sub-genre will hopefully expand even more in the coming years, securing its lasting legitimacy in the K-drama landscape.
