The story is great and the cast is also did a great job. 2nd season is more emotional based that's a good point and the other point is it's all about fighting with monsters to survive. About the cast, there are like too much people and it feels a little bit messy somehow. Way more different than the 1st season.

In the previous sason people complained that the military isn't doing their job but in this season the story is all about military, monsters and survival. I must say that the ending was unexpected and I really loved Song Kang's acting here. About the others their skills are also developed alot than the previous season even the editing are also way more realistic than the previous season. Comparing this to the 1st season something's off in this and I still can't figure it out. At some point I feel like the variety of the monsters here is way too much because it's never ending. One after another so when we give a thought about it it's like they're repeating the same thing over and over. Anyways overall I like this.

Hope everything will end better. There will be a season 3 for this and I'm hopefully waiting for it.
