I think if we don't get the OT cast again it's going to suck for me. Older Beast is much better than young Beast and we haven't even seen characters like Nightcrawler or Angel return. I feel like it's an overall waste of time to get these younger versions of characters that aren't the full-fledged characters we know and love. To have to wait for them to grow into those characters(after we've gotten great versions of those same characters in the OT) is too much of a chore. Like Beast. You're telling me I have to endure young Beast for yet another movie? So I get 3 movies of him and only 1 real movie with adult Beast? That's bulls**t.
"Oh, Beast sucked in First Class, but he'll be better in DOFP because he'll be the Beast I know and love."
*DOFP rolls around*
"...You mean Beast is still the same timid, growly voice-having kid who's appearance is altered with serum that he was in FC? The only thing that's really changed is his agility and look? OH, guess he'll grow more into the Beast I know and love in Apocalypse. Right? Right?"
