I know the canon, but they act so differently from the characters they're supposed to represent that I have a hard time accepting that they're the same people. It's not just that they're younger either. They're completely different people in most cases.

The biggest problem with teen Jean was her refusal to stay out of other people's minds even when they asked her to. In reality she'd be ostracized almost immediately for that behavior.
