“Sorority Slaughterhouse” (* out of four) was a grade-Z horror thriller that makes any of the crummy “Paranormal Activity” sequels look like “Psycho” by comparison. When the promiscuous dean (Eric Roberts) of a small-town college commits suicide, he is reincarnated as a clown who stalks the sorority sisters of whom he used to sleep with and blames for driving him to his death. Inept filmmaking and acting make this laughable and stupid. Movie reuses the film score from some of the “Friday The 13th” sequels, a reminder (as if we needed one) of the right way to make these kinds of movies. Everyone has to pay the bills- but can’t anyone rescue great ’80’s character actor Roberts from this unreleasable junk?
