Man. X-Men is becoming a very weird series, with all the prequels, sequels, and sequels to prequels, and now an alternate time/storyline.
I think this is why The Wolverine may not perform too well - it won't share any of the brightness of First Class and can only really hope to be better than Origins and simultaneously less bloated than The Last Stand.
I will however, keep going to watch these films...as Prof. X and Magneto look badass here.
Edit: oh fuck, looks like they didn't leave Shawn Ashmore behind. Arghgh.
