Putting my username and obvious bias aside, it's a travesty that Cyclops isn't in these films. Having him cut out of the X-Men movieverse is a huge loss imo.
Although First Class did, and DOFP probably will, "work" without him, it just sucks.
Aside from the disappointing sentinels, the Cyclops thing still drives me nuts (even when I manage to forget that Famke Janssen is 10 years older than James Marsden, which was always weird).
The whole continuity of the films seems like a train wreck now. And then take a classic storyline and put it all in a blender and voila...just doesn't seem satisfying (but none of the films were for me).
The fanboy in me is excited to catch a glimpse of any of the heroes on-screen, but the story and character development has been so weak it's almost non-existent.
Take Colossus for instance. He appeared in X2, has a bit more screen time in X3, but does he say much? Do we know his story? Do we have a reason to care?
Compare that to Sam Wilson/The Falcon in Winter Soldier.
