MCU Villains: Why so controversial when criticised?

Thor is not presented as an independent heroic character. He is seriously flawed, has parental issues, shown to be kind of dumb (like when he defends Loki in Avengers and is reminded that his brother killed 200 mortals-to which he responds with embarrassment.). Made the butt of a Stark joke. In Thor 2 he fails to defeat the bad guy-Loki and the earthlings do it.

The only male characters in the Marvel universe shown to be non neurotic or traditionally successful are Nick Fury and Black Panther (maybe we can throw in Rhodes and Falcon).

There is a color pattern emerging.
