I liked it I thought the movie was funny but I laughed at some of the serious scenes when no one else was laughing really.
(SPOILER) It was funny though because in the very beginning of the movie when he had the watch that checks his heart rate and stuff I remember thinking, "awww if he can't get his heart rate up he can't have sex..." and then they actually showed that in the movie. So when everyone was laughing around me I was just sitting thinking, "I already called that."
