As a seasoned viewer and critic of the genre, I’ve curated this list not just by scare factor, but by the distinct type of fear each series evokes.

1. Revenant

• Episodes: 12 episodes

• Cast: Kim Tae-ri, Oh Jung-se, Hong Kyung

• Where to Watch: Disney+, SBS

When Gu San-young receives a cursed relic from her deceased father, she unknowingly becomes a vessel for a malevolent spirit with centuries of rage. This is no ordinary possession—the vengeful child ghost that inhabits her has been denied justice for decades, and now seeks bloody retribution through San-young’s body.

As people around her begin committing mysterious suicides, folklore professor Yeom Hae-sang, who can see the dead, desperately tries to exorcise the spirit before it claims more innocent lives. But some evil is too ancient, too twisted to be easily banished…

Spine-Chilling Elements: Demonic possession, mysterious mass suicides, ancient curses, evil child spirits, exorcism rituals

2. Kingdom

• Episodes: 12 episodes across 2 seasons + Ashin special

• Cast: Ju Ji-hoon, Bae Doona, Ryu Seung-ryong

• Where to Watch: Netflix

The Plague of the Damned: In 17th century Joseon, Crown Prince Lee Chang discovers his father, the King, has been transformed into a flesh-hungry zombie by a mysterious resurrection plant.

What begins as political intrigue becomes a nightmarish apocalypse as the undead plague spreads across the kingdom, turning nobles and peasants alike into ravenous monsters that hunt only in the bone-chilling cold of night.

These are not slow, shambling corpses—they are lightning-fast killing machines that swarm like locusts, devouring everything in their path.

Terrifying Elements: Fast-moving zombies, medieval apocalypse, political conspiracy, resurrection plants, mass infection, cannibalism

3. Hellbound

• Episodes: 12 episodes (Season 1: 6, Season 2: 6)

• Cast: Yoo Ah-in, Park Jeong-min, Kim Hyun-joo

• Where to Watch: Netflix

Judgment Day Horror: Massive, otherworldly faces appear from nowhere, delivering death sentences to random individuals, condemning them to Hell at precise future moments.

When that moment arrives, three monstrous demons materialize—hulking beasts with vine-like appendages and burning light emanating from their hands—to brutally maul and incinerate their victims in spectacular public executions called “demonstrations”.

Society crumbles as religious fanatics declare this divine justice, but when the condemned begin returning from the dead, the very nature of judgment itself is questioned.

Horrific Elements: Giant supernatural faces, prophetic death sentences, public executions by demons, religious extremism, resurrection from Hell

4. Sweet Home

• Episodes: 30 episodes across 3 seasons

• Cast: Song Kang, Lee Jin-wook, Lee Si-young

• Where to Watch: Netflix

When Humanity Becomes the Monster: Cha Hyun-su, a suicidal teenager, finds himself trapped in a decrepit apartment building as humans begin transforming into grotesque monsters based on their deepest, darkest desires.

These aren’t random mutations—each creature represents the perverted manifestation of what people craved most: a ballet dancer becomes a spider-legged horror, a bodybuilder becomes a muscle-bound abomination.

As Hyun-su discovers his own monstrous transformation abilities, he must choose between his humanity and the terrifying power that could save the remaining survivors.

Nightmare Fuel: Desire-based body horror, psychological transformation, grotesque monsters, survival horror, human mutation

5. All of Us Are Dead

• Episodes: 12 episodes

• Cast: Park Ji-hu, Yoon Chan-young, Cho Yi-hyun

• Where to Watch: Netflix

School’s Out Forever: Hyosan High School becomes a blood-soaked battleground when a science teacher’s revenge experiment creates a zombie virus that spreads like wildfire through the student body.

Trapped students watch in horror as their best friends and first loves transform into flesh-craving monsters, forcing childhood friends to kill the people they once cared about or be devoured alive.

 In this school, graduation means survival, and the only lesson left to learn is how far you’ll go to stay human.

Horror Elements: High school zombie outbreak, student-on-student violence, viral infection, survival horror, coming-of-age nightmare

6. The Glory

• Episodes: 16 episodes (2 parts)

• Cast: Song Hye-kyo, Lee Do-hyun, Lim Ji-yeon

• Where to Watch: Netflix

Psychological Terror: Moon Dong-eun endured unspeakable torture as a high school student—her bullies burned her flesh with curling irons, leaving permanent scars across her body.

Now, years later, she has orchestrated an elaborate revenge scheme that will systematically destroy each of her tormentors’ lives. This isn’t quick vengeance—it’s a slow, methodical psychological dismantling that will leave her enemies begging for the mercy they never showed her.

Disturbing Elements: Graphic torture scenes, psychological manipulation, systematic revenge, school violence, trauma-based horror

The horror here is profoundly human. Unlike supernatural threats, the bullies in The Glory are terrifyingly real. This series is chilling because it explores a truth often scarier than monsters: the capacity for human cruelty and the lifelong scars of trauma.

The revenge is satisfying precisely because the initial injustice feels so visceral and plausible.
