Query: A True Nightmare!

This movie was very frightening. After I watched some of the dental torture scenes my teeth started to ache, but after I gave it a try. The music was really creepy and Corbin Bernsen did a wonderful job in this film. It kinda has that dark comedy tone to it. The mutilation parts aren't very pretty. Once you see them you will never want to go to get a checkup again. The scary thing is that this could happen in real life, but somethings are just dragged a little out of hand. The movie I still get nightmares about once in awhile. I can't tell why though that I'm addicted to this movie. I think it is because of Corbin Bernsen's(Alan Feinstone-The Dentist) performance. I know the dental torture is not my thing. If this sort of thing doesn't bother you give it a try otherwise stay away if you are very sensitive!
