I'd definitely watch an animated series based on the early years of the X-Men. Just Cyclops, Beast, Iceman, Angel, Jean and the Professor. I'd be all for it.
1989 - "That Batman movie was pretty good. I wish we had more comic movies..."
2015 - "Aunt May is too young, Aquaman isn't blonde, Apocalypse looks purple, and ALL THESE ACTORS ARE TOO SHORT! HOW COULD THEY DO THIS TO MEEEEE?!?"
