X-Men Origins: Wolverine
I actually enjoyed this a lot more then i was expecting to. I think thats because i was never particularly interested in the character of Wolverine as a kid, and so i really had no idea what his back story was, so it made it easier for me to watch the movie without getting frustrated every time they fucked something up. lol Towards the end of the movie though, when they brought in Gambit and Cyclops, i started to realize the discrepancies, but other then that it was not bad.
Also, i think what made me enjoy it a bit more was that it had a completely different feeling then the previous X-men films, so that kind of set it apart in my mind.
