If I compare S1 to S2, then I found S1 to be more interesting. But if I solely talk about S2 then there was a lot going on. Since in S2, they have come out from the apartment to the outside world, of course, there has to be some more characters to have the story going on and to make it interesting, but somehow it felt like that there were too many characters and it was difficult to grasp upon each character story. For instance, you weren’t able to understand their perspective or their point of view or what happened in the past to them more clearly, than I was able to understand of S1 cast cause there story has already been developed.
This season was more focused upon how soldiers are trying to fight and save people. A lot of screen time was given to soldiers and showcased how much they’re sacrificing just to save people. It also showed that how most of the people just thought about themselves and not about those soldiers who are risking their life for the people.
There are new kinds of monster in this season and some of them felt like they were robots, which I found a bit strange. It also showed how the monsters are afraid of humans. As humans can kill them any time and how they wanted to save themselves as well as the other monsters and that’s why they want to kill humans.
There were some part which I have found a little bit boring (maybe because I wanted to see song kang lol) but still it was a nice watch.
Since I am a die hard fan of song kang I didn’t like the fact that being the ML, he was given a very less screen time and dialogues and also the last episode last seen where eun yu and hyun su were talking and how their was a tension between them and then suddenly the scene got cut off and I felt so bad.(crying)
Music – S1 had some awesome songs and they are a part of my playlist even today. But I didn’t like the fact that they didn’t put any kind of music in S2 because in S1 there were a lot of comments upon how the songs are not matching with the scenes. So maybe that’s why the director doesn’t put any song in this season.

But overall I liked it. It was different from S1 and it focused upon some other things. They were few emotional scenes as well and I would recommend people to watch it.

Now about the fact that would I re watch it or not? Yes, I would re-watch it when the S3 will be coming lol.
WAITING FOR S3!!!!!
