Hmm. It wasn't too bad actually. Personally I don't find Wolverine's character very interesting, but I liked the appearances from Gambit, Cyclops, Sabretooth and the girl...I can't remember her name, but she could influence people :\
Plus the Weapon 11 was incredibly cool.
Aaah **** it, I'm an X-Men geek, I loved it.
And Will.I.Am's character was cool too :]
