The premise of GATE is amazing, and it starts off solid in the first episode. And then it quickly devolves into a showcase of the two worst anime tropes: Japanese hyper-nationalist jingoism, and loli-girl harem.
Had these show handled its invaders from another world theme more seriously, it would have been a damn fine show. Instead, no one in this universe behaves like a real person, or is realistic in any sense of the word. The entire purpose of the series is to show off how great Japan is and how idiotic the rest of the world is.
Oh, and it lets young dudes watching it imagine that they are the main character, surrounded by cute underage-looking girls that fawn over him constantly.
It's just sick, and very emblematic of where anime is right now, which is a bad place.
