Zombies are everywhere — but nobody had done them quite like Kingdom (킹덤). Take a classic Korean historical drama, all silk robes and palace scheming, and unleash a ravenous plague of the undead through it. The result is one of the most striking things Netflix has ever made in Korea: beautiful, terrifying, and smarter than it has any right to be. Here's my honest, friend's review.
I'll be honest about my own bias up front. I came to Kingdom a little reluctantly. I'd grown up with sageuk — the sweeping Joseon-era costume dramas my mother kept on in the evenings — and I am not, by nature, a horror person. I close my eyes during jump scares. I assumed a zombie show wearing a hanbok would be a gimmick, the kind of thing you watch for ten minutes out of curiosity and then quietly turn off. I was wrong, and I was wrong fast. By the end of the first episode I had texted two friends. By the end of the first season I was furious there were only six episodes. This is one of the few times the hype around a Korean show was, if anything, an understatement.
No major spoilers beyond the setup.
My honest first impression
The thing that hooked me wasn't the zombies. It was the silence before them. Kingdom opens slow and cold — a sick king sealed inside his chambers, a court thick with rumour, a starving country where people are quietly eating things they should not be eating. For a long stretch you're watching a tense political drama about a son who suspects something is deeply wrong with his father and the men who rule in the father's name. The horror arrives almost as confirmation of a dread the show has already planted in you. That patience is what separates Kingdom from the dozens of zombie things I've half-watched and forgotten. It earns the running before it makes you run.
And when the running starts — it really starts. I am not exaggerating when I say the first proper outbreak sequence made me put my tea down. The dead in Kingdom are not the shambling, groaning kind. They sprint. They swarm. They pour over walls and through gates like water finding a crack, and the show shoots it with a kind of cold horror that doesn't beg you to scream so much as tighten your stomach until you can't breathe. I watched it at night, alone, which I do not recommend and absolutely recommend.
What It's About
In a Joseon-era Korea wracked by hunger and corruption, Crown Prince Lee Chang grows suspicious about his father the king's mysterious illness — and the powerful clan controlling the throne from the shadows. His investigation leads him to a horrifying truth: a plague is turning the dead into ravenous monsters that hunt the living, and it's spreading through a kingdom too divided and starving to stop it.
As the outbreak races south, the prince — branded a traitor — must fight to survive, protect the people, and expose the clan exploiting the chaos for power. At his side is Seo-bi, a sharp physician who understands the strange resurrection plant at the root of it all. It's part political thriller, part survival horror, and entirely gripping.
What I love about the structure is how the two threats — the plague and the politics — are really the same threat wearing two faces. The clan in power, the Haewon Cho family, would rather hide the outbreak and protect their grip on the throne than warn the people. The dead spread because the living lie. By the time you reach the second season, the show has quietly made its argument: the monsters were never the most dangerous thing in the kingdom. The most dangerous thing was a ruling class that decided ordinary lives were expendable. For a zombie show, that's a genuinely sharp idea, and Kingdom commits to it without ever stopping to lecture you.
The cast & characters
A show like this lives or dies on whether you believe its people, and Kingdom is anchored by performances that take the absurd premise completely seriously. Ju Ji-hoon (주지훈) plays Crown Prince Lee Chang as a man slowly hardening into a leader — he begins almost soft, a sheltered heir more comfortable with grief than command, and the season-to-season arc of him becoming someone people would follow into a wall of the dead is one of the quiet pleasures of the show. He never plays it as heroic posturing. He plays it as a person being forged by horror.
Then there's Bae Doona (배두나) as Seo-bi, the physician, and honestly she's my favourite thing in the whole production. In a genre that loves to make its women scream and run, Seo-bi is the one keeping her head — observing, dissecting, working out the biology of the plague while everyone around her panics. She's the show's brain, and Bae Doona plays her with this steady, unshowy intelligence that makes the science feel real. Ryu Seung-ryong (류승룡) as the clan leader Cho Hak-ju is the kind of villain who never raises his voice and is more frightening for it — a man who treats the throne like a board game and human beings like pieces.
And a note for fans who arrive after season two: Jun Ji-hyun (전지현), one of Korea's biggest stars, appears in the closing moments as a mysterious figure tied to the origin of the plague, setting up the standalone special Ashin of the North. If you finish the two seasons wanting more, that special is where to go next — it's a feature-length origin story, darker and sadder than the main run.
What it does well
A genuinely fresh idea, fully committed to
Zombies plus a meticulously detailed historical Korea shouldn't work this well. The combination feels new, and the period setting makes the horror hit harder — there are no helicopters, no guns, no phones to call for help. When the dead come, all anyone has is a wall, a gate, a sword, and the daylight. (The show makes brilliant use of one rule: the dead sleep when the sun is up. That single mechanic turns daytime into a desperate countdown.)
It's stunning to look at
The production design — the hanbok, the iconic wide-brimmed Joseon gat hats, the sweeping mountain landscapes and fortress walls — is film-grade. Director Kim Seong-hun and writer Kim Eun-hee, who adapted it from her own webcomic The Kingdom of the Gods, shoot it like a prestige cinema epic. Even at its goriest, it's beautiful. There's a reason a wave of international viewers suddenly wanted to know about the hats.
There's real substance under the scares
Underneath the horror is a pointed story about hunger, class, and rulers who fail their people. The plague literally spreads through the starving and the desperate; the show keeps drawing your eye to the gap between the people in silk who hoard food and the people in rags who are reduced to the unthinkable. The "the real monster is power" theme could be heavy-handed and somehow never is.
Tight, bingeable, and unafraid to be short
With compact six-episode seasons, it never drags and never pads. That's rare and precious. I'd rather have twelve lean, perfect episodes than a sprawling twenty that lose their nerve, and Kingdom clearly agrees.
What might not be for everyone
I want to be a fair friend here, not just a cheerleader. Kingdom is genuinely a horror series, and the violence is real. There's gore, there are deaths of sympathetic people, and the tension rarely lets up for long. If you're someone who watches K-dramas mainly for cosy comfort and slow romance, this is the opposite of that experience — there is no central love story, and the show is not interested in giving you one. Go in expecting a tense survival thriller, not a feel-good binge.
The other honest caveat is the ending. After two seasons, Kingdom stops on a deliberate cliffhanger that sets up a future the show hasn't yet delivered in full. The standalone Ashin of the North special expands the world and answers some questions, but if you need every thread tied off in a neat bow, you may finish feeling that the story is paused rather than concluded. I didn't mind — I'd happily watch more — but it's worth knowing before you start so the final shot doesn't catch you off guard.
And the politics, while never boring to me, do ask for your attention. This isn't a show you can half-watch on your phone. The clan intrigue, the court factions, the question of who really controls the throne — it rewards you for following closely, and it can feel a touch dense in the early going before the outbreak takes over. Stick with it. The patience pays off.
Who should watch this
Kingdom is for you if you like your horror with a brain and your historical dramas with stakes. If you loved the social bite of Squid Game or the dread of a good survival thriller, this will land. If you've always been curious about sageuk but worried it might be slow or stuffy, Kingdom is a thrilling side door into the genre — you get the gorgeous costumes and palace politics with a pulse-pounding engine driving it. And if you're a horror fan who's tired of the same modern settings, the Joseon backdrop will feel like a gift.
It's also, frankly, a great "convince a skeptic" show. The friends I sent it to included two people who insist they don't watch subtitled anything, and both came back having binged the whole thing in a weekend. There's something about the universal grammar of horror — run, hide, survive — that crosses the subtitle barrier instantly.
One more group I'd specifically recommend it to: anyone who appreciates craft. Kingdom is a masterclass in how to build dread, how to stage a set piece, and how to use a single rule (the dead and the sun) to wring tension out of every sunrise and sunset. If you're the kind of viewer who enjoys seeing a thing made exceptionally well — the costuming, the camera work, the way a quiet courtyard becomes the most frightening place on earth — this rewards close attention. I've rewatched the first outbreak sequence purely to admire the construction of it. That's a rare thing to be able to say about a zombie show, and it's why Kingdom has stayed with me when so many others blur together.

Where to watch it
Netflix is the exclusive global home for both seasons plus the standalone special, Ashin of the North, with subtitles in many languages.
It's a Netflix original, so you won't find it legally anywhere else. The good news is that means it's the same place worldwide — no hunting across regional catalogues the way you sometimes have to with older K-dramas. If you have Netflix, you have all of Kingdom.
One small piece of viewing advice from me: watch the two seasons first, in order, and only then watch Ashin of the North. The special is a prequel, but it lands far harder once you already know the world and the weight of what's coming. Going in order also means the cameo at the end of season two pays off exactly as the writers intended.

Frequently asked questions
Two seasons of six episodes each, plus a standalone feature-length special called Ashin of the North that serves as a prequel and expands the origin of the plague. All of it lives on Netflix. Watch the two seasons first, then the special — it hits harder in that order.
Yes — it's a genuine horror series with fast, swarming zombies, real violence, and the deaths of sympathetic characters. It's not gratuitous; the gore serves the dread rather than wallowing in it. But if jump scares and tension aren't your thing, go in prepared. I watched it alone at night, which made it more thrilling and also a slightly poor decision.
Not at all. The Joseon-era setting is gorgeous, but Kingdom plays as a survival horror-thriller first and a sageuk second. There's no homework required — the show explains everything you need through the action. If anything, it's one of the best gateways into Korean historical drama precisely because the horror engine pulls you through the politics.
No — and that's worth knowing going in. Unlike most K-dramas, Kingdom has no central love story. The relationships that matter are loyalty, mentorship, and the bond between people trying to keep each other alive. If you come to K-dramas mainly for romance, this is the exception to the rule.
Kingdom is the rare genre mash-up that fully delivers — a stunning historical drama and a genuinely scary zombie thriller at the same time, with something real to say underneath the screaming. It surprised me, it converted my subtitle-averse friends, and it's the show I point to when someone claims they "already know what zombie stories do." If you want something that looks gorgeous and keeps your pulse up, this is essential viewing.
