Honestly, I cannot understand the negative reviews with things to complain about. I am someone who enjoys complexity in morals and the difficulties of human relationships with each other, morals, desires, and greed. This is a series that touches on so many topics while still holding senses of morbidity, romance, and humour. The main couple, in my opinion, are fantastic and their characters are actually well thought through, from their backstory, to the way they grow up, and the way their history together effects their relationship in the future. the side characters have such a variety of relationships and struggles, with a real focus on classism (as a lot of K dramas seem to have - rich Vs poor, hard working Vs easy living).

I really loved this and honestly, it's one of the best zombie based series I have seen so far aside from maybe all of us are dead. The virus in this acts different from a lot of other series and I think it really allows for a lot of character and plot to be built on as even people who have been infected can continue on and have a hopeful happy ending. Bringing that bit of humanity to monster, and showing the monsters of humanity, it's truly a beautiful juxtaposition that makes you question so much.

the only thing I wish was that maybe they had left more time to fully establish the ending of other key characters like the antidote efficiency, what happens to the rich guy, what happen's to Han Taeseok's wife and child. there was a lot left undisclosed however it isn't too much of an issue for me personally as open endings often allow for own interpretation. I'll mention it as this may have been off putting for some people, yet this is the thing I have seen less addressed over "wah, they had plot armour as the main characters, how annoying".

TLDR; if you are looking for a series that you can sit down and mindlessly watch, I would say this isn't for you. if you go into this series mindlessly, you miss the entirety of its meaning and story. 10/10 would watch again and would recommend to people who value the art of storytelling. also, if you just want a zombie flic, this also isn't for you; this series is very much based on human interaction and the behaviours of people stuck together in a situation that is not exactly pleasant, with people who are even less pleasant. (I'm honestly tired of people going into series with an expectation and then rating it lower all because it wasn't like the others they watched - that is a good thing.)
