I will second Josh's most eloquent appraisal with an all encompassing DAMN RIGHT MOTHERFUCKER!!! I was spooked for several hours after seeing that fright-fest on the big screen. Bill Mosely did an amazing job and Rob Zombie's wife was hot as always especially during the aforementioned Bettie Page scene.
See it in the theatre. That is the only way to enjoy the cinematic mind fucking that this movie gives.
