I've seen many SK historical dramas with various sub-genres. If you take the sub-genres aside, KINGDOM is the best historical drama. Who knew that historical drama featuring zombies would be a perfect mashup? Usually, I watch a drama because of its casts (I prioritize watching dramas if my favorite actresses are there). In this drama, however, I didn't know who the casts are at all, so this review would be more objective.

Genre: History
Sub-genres: Thriller, horror

Pros:
- No romance sh1t. I mean there's a lil romance aspect in it, but it doesn't affect the solidness of the plot.
- Solid plot. Trust me, there's no wasting time. Every second in this drama has connections to other scenes.
- Easy to understand the story.
- No plot holes.
- Unique characteristic of zombies. It's not like zombies you've found in other dramas.
- Within 6 episodes, you get political, horror/thriller, and mystery aspects.
- Endless breathtaking actions
- Mini plot twists that make you wonder all the time what caused the epidemic.

Cons:
- It's too short :( 6 episodes each season (1 hour per episode)
- As always, you will find it hard to remember who is who.
- Lack of comedy, but some are still there.
