Gatchaman Crowds

The protagonist is a literal happy-go-lucky mary sue who despite being told multiple times not to do something, does it anyway and gets away with it because she can do no wrong! Often times her overly cheerful demeanor is obnoxious and grating, while also displaying no flaws or variety in character, making her totally one-dimensional. Aside from that, the show barely features any action for a show about Tatsunoko superheroes and dives head first into really pretentious dialog trying to be deep.
