wow! awesome movie. Saw it opening night and was not expecting it to be as good as it was. Definitely check it out! It's 79% on rottentomatoes.com, better then all the other new movies it opened with.
I still think that little blue guy is just Seth Rogen reincarnated as a little fury blue creature and not as a character who I totally believe is real. But anyway thats just my little beef with the voice acting.
