I saw it last night. I didn't like it. Other people were laughing, but I didn't find many parts funny. Just not my kind of humor anymore.
When I was in third grade I loved the simpsons, but I think my sense of humor has matured over the last 10 years. I prefer more witty stuff, and less about silliness for silliness' sake. Heck, even South Park has some similar humor with being silly or rude, but at least there are underlying issues that the creators try to tackle. I wasn't surprised at how lackluster the movie was, anyway. I quit watching the show for a few years now and it has been going downhill for a while.
