I loved the first part so much, i think it did quite a good job but the second part is where it all went down hill. Where did Won Bin go ? He was with the class and the next season he wasn't. Maybe the actor couldn't film or they didn't want to write his character in but they could have at least did some goodbye or mention where his character had left to.

We're transported into this new place where the characters have well, changed drastically since the leaders passing, which i honestly thought the character development had gone quite well.. well that was until the ending.

To get started, the kids break up into teams and continue killing the spheres and going out for ammo, food, resources, etc. This results into two of the biggest events in part two, the prison scene and one of their friends dying and they don't know how. The prison scene i think was one of the worst scenes to happen in the show but i can let it slide if it was necessary for the plot. however i think the sexual assault scene was completely unnecessary and did nothing but show that BoRa actually did care for Ae Sol all along. But that couldve easily been portrayed in other ways. The classmate's death was semi necessary to create animosity between the characters but i hated how they portrayed it to be something suspenseful just for him to have fallen to his death because of the spheres..

The ending though is really ridiculous as we have another sexual assault scene followed up by everyone's death. Yeong Soo's character in general was so horrible from start to finish. He's poor so he still cares about college while the world is ending ? i suppose there could be someone out there like that but it still felt so pointless. Then he starts hallucinating and going "insane" and sexually assaults soyeon all because he continously made creepy advances towards her and then felt insulted by her ?? then hallucinates and kills his whole classroom because "no one can find out what happened" as if the bodies with gun shot wounds won't be retrieved later?? it all just felt like a very lazy and unjustified ending. I don't mind having only a few survivors at the end but .. that was a horrible way to go about it honestly. Maybe that was supposed to be the point though ? to not give hormonal, stressed, angsty teenagers hold mass weapons of destruction ?? regardless though, there was so many plotholes and the ending was done very poorly.
