This is a really bloody movie. Still it was excellent and I'm very glad I decided to watch it. I will tell you a little about the movie. I don't want to tell you to much in case you decide you want to watch it. Here it is in a nutshell. These teens attended high school. They were rough, little trouble makers and never showed any respect to their teacher. Because of them, the teacher couldn't get control of his class.While he attempted to teach they were continuously disrupting his class. They even went as far as putting chewing gum in his hair and writing things on his car with a knife. And that's just the tip of the iceberg. Eventually the teacher has enough of it. Don't worry because he does gets his revenge on the teens.That's all I going to say in case someone else might want to watch it.
