Not anymore, but outside of Superman and other assorted DC books, I grew up on X-Men, particularly X-Factor. They were some of the first Marvel comics I was ever subscribed to. Got very much into them during the launch of X-Men #1 (still have all those freaking covers), and was subscribed to every book, save Exacalbur, all the way up and through the Age of Apocalypse (in which I added Excalibre to keep up with the storyline).
Stopped with all the books somewhere around Onslaught, as I just didn't enjoy them anymore. My bias towards DC has only grown more and more since then, but I've considered picking up X-Factor because the thought of a book with that title, the characters involved, and the words "Written By Peter David" all put together just make me feel nostalgic. If it weren't for my lack of funds, and the relaunch of Wonder Woman and JLA on the horizen, I probably would.
As for the changes from the comics to the films, they didn't really bother me, including what's found in this one. It's probably because I was never a huge fan though. I suppose if I had more of a vested interest in the source material, or in one of the characters who got screwed (Cyclops), it would. As it is though, I enjoyed each film for what it was, changes or not.
