If you’re looking for Sci-Fi, this is a terrible show. It randomly crams in a bunch of feminism, lesbian, and extramarital affairs.Its fine but I didn’t even see any aliens until the second half, and the setting is pretty sloppy. For example, in space hinata can just wave her hands to move around. Yamato’s arguments make absolutely no sense, and the characters don’t feel like technical experts at all—more like jiraikei walking around the streets of Shibuya.
