Likes: As a fan of the zombie genre, I thought the production was pretty good. The action scenes were tense and nicely done. It was entertaining enough that I don't regret watching this.

Dislikes:
- There were no real likeable characters. No one stood out. And because the characters weren't fleshed out enough, I didn't feel a connection with any of them so I wasn't really rooting for anyone that strongly. Nobody really left an impression.
- I especially didn't like the character of Ohn Jo. She was so dull (as with most of the female characters for most of the drama) Having one of the main characters be so dull was a wrong move.
-Lack of clear leads. I wasn't sure half the time who were supposed to be the main leads. Is it Cheong San/Ohn Jo? Or is it Nam ra/Soo Hyuk? I think if the drama had focused on the Nam ra/ Soo Hyuk arc , fleshed that out a bit more and also the hybrid changes that Nam ra was going through, the drama would have been more interesting.
-Lack of depth in the story arcs. Like what was the purpose of the detective, his partner, the baby, and little girl? They added no value to the story. And the whole arc of Ohn Jo and her father was kind of a let down. And the purpose of introducing the arrow shooting nuna so late in the game?
-Draggy moments. Not gonna lie. I did FF a little in the draggy parts.

Overall disappointing? Yes, but I was still entertained enough mainly due to my love for the zombie chase. Would I watch this again? No. Would I watch another season? Yes, esp if they concentrated on the zombie hybrids and have cool action scenes.
