My gal and I made the mistake of going to a Saturday afternoon show. Ten-year-olds as far as the eye could see. Eeesh. The one sitting right next to me couldn't stop jiggling his foot against mine (darn parents filling their kids with sugar!). Still kept doing it after three times telling him to stop. Fortunately, my girlfriend pointed out an empty seat on the other side of her; good thing too -- I was ready to kill him!
As for the movie, I thought it was pretty funny. The human characters were the least interesting parts, and Steve Carrel was a blast. The scene where he drinks the caffeine and the world stops is great. "But I like the cookie," has become a new catch-phrase in this household!
