the claws did look weird, but you can't go into the movie trying to nitpick everything, or maybe i just really wanted to like it & the girl I went with was really into it, so I was too.
I was willing to overlook certain things in the movie just so I wouldn't be over critical and take myself out of the experience. Like wolverines claws looking like a 1st year CGI student at Dan's School for Animation did the effect making them look too silvery, or the fact that now Gambit was over agile & took a few abilities from the game Xmen Legends II, or the fact that Deadpool had swords coming out of his hands that were so long, that he wouldn't be ale to bend his arm if he had them retracted, not to mention swords coming out of his hands and the cyclops eyes (did they also steal teleportation from his power set in Xmen Legends II?).
The helicopter scene was much better than people had said it was, and the action in general I thought was done pretty well, barring a few effects that made things look a little weird, like motorcycle coming out the exploding barn scene.
I find how they treated Deadpool a little weird considering they knew they planned on doing a movie just for him after this movie made its mark in the theater. How doe they explain away the sword claw & the cyclops eyes (& the teleportation if he's not supposed to do that).
