Oh yeah, it was too long! Did you finish your 15-season marathon of it? I can't imagine. ^^;;
Another one was The Walking Dead. It was why I praised “All Of Us Are Dead”, while they're not the same other than being in the zombie genre, the idea of survival and the various human emotions, mindset, combined, are similar. Yet, AOUAD was able to do in one season what multiple seasons of TWD tried to do.
