My impression of Charles was that in a lot of ways he's a typical 20-something when the movie starts - hence awful-but-hilarious-in-their-awfulness pick up lines, and his double standard over his little sister (also, that is so Truth In Television, from what I know of older brothers, which is not much but still). A lot of the other issues for him, to my mind, were that he's a mostly good-intentioned guy, but they took him from 20-something to putting Patrick Stewart-type lines in James McAvoy's mouth. Guys, guys! He's not old enough to be the venerable Professor X, I highly doubt he had this philosophy so very developed already!

Also, I think you've just made me realize why this film is making Charles/Erik try to push my longheld Magneto/Mystique ship into second place. Snarky domesticity. (Is a snark!kink possible?)
