Honestly, just 2 words: Less pandering.
I don't want characters created to appeal to younger demographics, or female demographics, or minority demographics. Of course, I have no problem with a varied cast throughout all roles, but I don't want the designed by committee thought process of "we have a female protagonist, because we NEED to have one". If it does, fine, but don't make it like you are filling a checklist or something...
Also, I would like the movies to be less guided toward the merchandise proposals and diversity. It is SW and Disney, so of course it will. I just settle with "not embarrassingly so"...
