What I didn't like about the X-Men movies is they just kept the same and continues the story. And that's a big gripe I have with Marvel too.

Let comics do their thing, have new stories and new arcs instead of some 20+ hour cinematic universe. Its comics, they don't all have the same continuity. And stop telling origin stories, we know how the superheroes became superheroes, and even if the audience didn't, it doesn't matter to be able to tell a story with that character anyway.
