part 1 (ep 1-6)
i went in knowing nothing and finished ep 6 with very high expectations for any other drama in this same genre. its very stupid to make highschoolers train for war but its fiction so whatever. everything was really cool, the story line was unique and the acting was perfect. some characters were annoying throughout every episode but i had to cut them slack because yk a war, high school kids, a lot of fear and stress. when i finished it i had very high hopes that a certain someone would come back to life magically but i still didnt think it would affect too much the next episodes whether it happened or not.

part 2 (ep 7-10)
honestly i think the writers just didnt know how to wrap it up nicely. i feel like they lost track of the actual story line from part1 because suddenly the spheres werent the main issue anymore. the end was understandable but at the same time it didnt make sense??. in my opinion if they just wanted to kill everyone they shouldve let the spheres do it instead of turning it into the mess that mass killing was. i know it is a realistic consequence of giving kids gun and the stress and trauma of being part of something apocalyptic but bro if i wanted to see that i could just turn on the news because sadly theres a lot of news like that in my tv. and then the drama ended and we still dont know why the spheres were there, where they came from or anything. really disappointed but i got too attached to the characters to say harsh things

i would recommend it because it was really something good and different and i think everyone can make their own opinions and thoughts on their own. dont know if everyone would like it tho
