Query: A Great Movie -- IF YOU'RE RETARDED!!!!

I watched "spiderman 2: the waffle cone experiment" last night. after watching it, i thought about all the good reviews it got and all the money it made and all the people who said it was better than the first one, and then i almost committed suicide. if i had actually paid $9 to see this, they'd still be finding pieces of my skull in the men's room at loews.but seriously, this is a really bad movie. all these people here on amazon who are calling it the best movie of the year should punch themselves in the face.
