It was not necessarily Adam Sandler's best work, but enjoyable. I personally enjoyed most of the humor. I took my 14yr old niece to it figuring that it was PG-13 and it would be okay, but i soon realized how inappropriate it was. Even she felt embarrassed throughout the film. If anything, this should have been more on the rated R side for the amount of sexual content being said.
I can honestly say they didn't screw this one up. Like everyone else, I was REALLY looking forward to this movie and it was awesome at every second of the film. The story, cast, and animations were just absolutely phenomenal! Robert Downey Jr. outdid himself with this one. Would definitely pay to seeing this movie again!
