CGI claws were a bad choice, but I didn't think it was overly distracting.
Jackman, Schreiber, (and even though his part was infinitesimal, Reynolds) carried this one for the most part. Danny Huston was average at best as Stryker, and Taylor Kitsch didn't really sound like Gambit, but Gambit is still really cool.
I must respectfully disagree with a previous reviewer; I thought they nailed Wolverine's emotion perfectly, especially in the scene (in the trailer) where he's battling Stryker's men in the Humvees and the helicopter. I thought the intense, animalistic rage came through very well in that scene.
Making a movie about Wolverine was a risky venture because of his fanatic following, but I think they did quite well.
