I think the best way to do the X-Men is to do a live action show with a budget like GOTThis is why i hope Kevin Fiege doesn't even do an X-men movie at first when marvel gets the right back. Instead establish all the most popular characters in their own solo films before teaming up like they did with the avengers.
Or maybe not even solo films, some of them could have cameo's in other shyt first, like Kitty pryde could be one of Peter Parkers classmates.
