Let's be honest first of all it's not really a horror.

I did like the story because it's not your usual k-drama but something different.

I do think there are a lot of unnecessary scenes and deaths (especially on-jo father) how he died was just stupid ?

Story writing is logic in some moments and some moments is just not.

I like that only the city is infected first and not like other series where you get first zombie and then immediately one episode later the whole world is infected...

Overall I did enjoy watching it, I liked how the characters are written too, it was great to watch for the first time but I wouldn't rewatch it, I do look forwards to the second season ;)
