I got a chance to get out and see Wolverine this weekend, and I have to say that I enjoyed it for the most part. Obviously, my biggest complaint was probably the treatment of Deadpool as well. I would have rather that just been a clone or some other completely new mutant if that was the route they had to take (having the "ultimate" mutant for the final battle). That said though, I went to the movie with my best friend, who hasn't ever read a comic in his life, and he didn't seem to have a problem with it at all. His only knowledge of the X-Men comes from the 90s cartoon and the previous movies, and he wouldn't have known the difference with Deadpool if I hadn't explained it to him afterwards. From that "general public" point of view, I don't know if it will matter to movie goers.
Overall though, it was a fun summer popcorn movie, and I think I liked it better than "The Last Stand" as far as the X-movies go. Jackman of course continued to be great as Wolvie, and I thought Ryan Reynolds was perfect as Deadpool/Wade Wilson - particularly in the early part of the movie before all the Weapon XI nonsense. I'm happy to hear that he's likely getting his own movie, that could be really good. I actually thought Taylor Kitsch was pretty good as Gambit, and it was cool to see him included in the flick. Although there were a crazy amount of cameos, I can't say it wasn't cool to see some of them included. Overall, a pretty good movie, I'll definitely be grabbing the DVD (or blu ray if we have it by then).
