^^ yeah well, thats what they've always done on the x-films, drop interesting character relations because theyre too lazy.
I loved x1 and x2, but at this point, I'm so tired of them just throwing characters at the screen with no character development.
Can they incorporate 4 new X-men in the middle of an Apocalypse story?? Sure, but they will get little to no development if they do. Maybe young Jean and Scott get some facetime, but then Storm, Nightcrawler, and Gambit will get shafted, especially if Wolverine's around.
Look at FC, we had a ton of new characters, and the only ones who got real development were Xavier, Beast, Magneto, and Mystique (all pre-existing characters too) Everyone else was barely a character. Havok and Banshee? I don't know **** about em, and one of Havok's most important relationships was totally deleted. And that was in a much smaller scale story than Apocalypse has to be.
I wish they would just pick a core X-team and build the films around them, as opposed to trying to fit every mutant ever created into an X-film for 5 seconds.
Your lists are pretty good, I would love to see Cyke, Jean, Beast, Storm, Wolverine, Nightcrawler, and Gambit as the team (with Colossus, Psylocke, and Iceman thrown in, if I had my way) I'm just afraid they won't be developed the way they need to be.
