On positive side: The casts and their acting is good. They do good job on their character. The music is pretty good. Liked the OST at the end of the show. Thats all the good thing about the show. I was looking forward to this show as this was unique compared to other apocalyptic shows. I liked the setting and the casts so I had high hopes. First part of the show is pretty good but not impressive. Still very watchable and also good enough for rewatch but whats up with the 2nd part? Who wrote this story. How does this even make any sense to end the show like that. Sure some people may be pretty crazy about their grades and achievements from school but this is too much like damn. I watched all 10 episodes and all for this half based ending that doesn't even make sense??. Yup I am nobody to write this kind of review but if you guys got too much time to waste, this show is the one. What a waste
