Let's see...what movies have I seen this summer so far...:
Mission Impossible II: Ok, it was pretty interesting, but it only got real good towards the end. So basically, you'd be paying $8.50 for 35 minutes worth of action.
Big Mommas House: It was OK. If you want to see it, catch a matinee( I hope I spelled that right

Scary Movie: Ok, I really enjoyed this movie. It was extrememly silly. Go with a bunch of your sorors and you'll have a blast

Shaft: A definite movie to see. If you see nothing else this summer-see Shaft-can you dig it?
I hope I was of some help
