As a comic book educated person, I have to say that I despise the X-Men movies for straying so far from the comics. However, on a purely movie going standpoint...I loved Wolverine. I realized a while ago that I wasn't going to get much accuracy between movies and comics.
***SPOILERS***
I too loved Liev Schreiber. The man was genius. I was honestly scared whenever he shows up. Wow.
Gambit is and always will be one of my favorite characters. Although he is supposed to be with Rogue!!! And um, yeah no sign of a real Cajun accent. Southern yes, but not enough French.
Ryan Reynolds as Wade Wilson is great. Definitely best lines of the movie. The whole creation of Deadpool completely sucked since its so off but in an interview Reynolds mentioned that he would love to do a Deadpool Origins and be 100% faithful to the comics and he didn't care if that didn't match the movie. (Also, (major spoiler!!!) Weapon XI isn't really Wade/Deadpool)
