I just first want to address the fact that Kingdom is a historical drama if it isn't obvious enough already. Why did I point that out? I've seen a few being turned off with the political aspects of the drama when that is something considered normal in a historical drama. So to those who might be reading this review, make sure you understand that part because you wouldn't enjoy this if you don't like politics in dramas.

Story: This is the first historical zombie drama I have watched (Idk if I can classify GoT as one lol) and the whole zombie plot was unique to me. I could give this a 10 out 10 but it still felt lacking in terms of the story of the characters. It will probably be expound on the next season but since I'm only rating for this one, I'll give it a 9.5.
For the politics, it's a scenario I've seen in many historical dramas before but it's surprisingly well-executed here, so i'm not gonna criticize no matter how common of a plot it is. There was parts of the politics that were fairly new to me so it wasn't completely predictable.

Acting/Cast: The acting were great for both the alive and the dead characters lol. There were some humor thrown from here and there and it sometimes come out as awkward so i couldn't really rate it a perfect 10. I guess that's like a signature moment in kdramas but I think it would be better if they just create an entire serious atmosphere throughout.

Music: Not much about the music since it didn't have the famous osts we know but I rated it a 10 for the fact that it sounded like a GoT intro lol

Rewatch value: Would definitely rewatch this again once season 2 is about to come out
