Urban Legends

This is one of my many problems with poorly constructed "horror" movies. I know that it is all an act, but are we really suppose to believe that Rebecca Gayheart could put a noose around Joshua Jackson's neck and pull him on top of a car? Also, she was shot, fell out of two story window, crashed through a windshield, and landed in a river and looked perfect only a year later? Why don't these villians die honorably like an average human being? Not only was I not impressed but the scare factor was nonexistent.
