Basically, and I think going in on stuff like menus is an example of that. People turned what is a pretty insignificant point into this emblematic thing about the whole presentation of the game, just streeeeeetching it to having meaning through this deep analysis of every crevasse of the game to find other things to be upset about. It's a fucking menu and most games have similarly or equally shitty menus, great games otherwise have shitty menus. It's such an incredibly dumb and menaingless point that's now another layer of dissatisfaction because we need to make sense of it all.
And then this sentiment ripples through the community.
And then this ripples through the reviews (the IGN video review sounds like it was written by someone on /b/) and sales.
Again, like you said, there are legitimate complaints about this game and a hell of a lot about them that can give anyone good reason to skip the game or feel a type of way towards Capcom. But that extra stupid shit has been given so much disproportionate meaning when people have open license to demonstrate how unsatisfied they are.
