Well, there's your problem.
You instantly assume that, because you didn't like it, no one liked it, but everyone is choosing to let it slide. Your statements make it seem like you can't comprehend why anyone could like the Avengers just because you didn't.

Superman is an archetypal story that's been mimicked and parodied to death. The primary criticism I've read concerning Man of Steel (Outside of the massive property damage) is that it's another origin, and considering most people knew Superman's origin before they could walk, it's valid.

Anyway, Avengers has it's own flaws and issues. No one is saying it doesn't and no one is denying it. However, you're assuming that, because it shares flaws with other "Popular to hate" movies, it means we have to either put up or shut up, despite films like Bay's Transformers having more glaring and jarring flaws that people loathed, not just "This one part was inconsistent with this other part."

If you compare the Avengers to the Transformers in complete seriousness, it's hard to take your statements seriously because they're different in almost every respect, the only real similarity being "They're action films."
