Scary Movie (1) is a classic that I love to watch.
Every one after is just pitiful. It especially went downhill after Keenan Ivory Wayans quit being involved after part 2. When David Zucker started directing part 3 and on, it just got stupid. Some parts and jokes of the films were hit-and-miss, but the majority of them were just awful.
I liked the First and Second a LOT. The third one it was just like...ok, it was decent. Don't want to watch it again though. It was funny but it was nothing like the first or second. I didn't even go to see the 4th movie, I mean they were making fun of things that weren't even horror movies...It looked sad. And after Epic movie I'm not sure I want to see anything else they make.
