Mostly on the screen appear shambles and slaughter.
It’s a kind of concept. The more slaughter and dead body - the better.

I don’t think that the story is addictive and interesting. It’s rather simple and uninspired. The characters are flat. It’s difficult to bond with anyone here.

But it’s watchable because of Joo Ji Hoon. His performance is brilliant! I like his prince who in the beginning of the story is confused and uncertain, but later, after some battles with zombies, becomes a true lead. The other acting is just okay. Nothing special. Definitely it’s too short (6 ep.) to develop plots and characters.
I don’t like the music. It would seem that especially music would create the dark mood and fear in the zombies world, but no. Not in this case.

If you don’t like a story that stopped and doesn’t run anywhere, do not watch it and wait for the next season.
Maybe the next season will be better, who knows.
