do not watch the last episode oh god do not watch the last episode it's just don't do it it's not worth it so anyway it's a fairly good show (fuck that one scene in the last episode). It has a lot of "fan service" which i usually don't like, but it never feels forced, and also i know alot more about survival situations than i did before (even things i don't wanna know, that one scene in the last episode is...). The story makes enough sense that you won't question it during a casual viewing, but it isn't perfect as most plots aren't. there are alot of flashbacks especiallylater on, and it can get kinda annoying but they're pretty short so it's not all that bad.
