I watched the other Scary Movies, and they were idiotic! However, this movie, while being partially ruined by so much... dumbness... had some hillarious jokes; for example, Cindy asks directions from a ghost so she can go to the Village. A message forms on the wall in blood, and Cindy says, "Hey, I can't read this!" The message reforms into a Yahoo! maps map, and Cindy says, "Ah, that's better!"
Sometimes it's OK to just watch something mindless, and this movie is a good way to do that. It is very inappropiate, yet funny.
