It's hard to find horror movies that haven't taken some kind of thought or idea from a previous one but Dario Argeto's ("Tenebre", "Susupiria", "Deep Red") Creepers seemed to be in a class all by itself (at least to me anyway).
Jennifer Connelly plays Jennifer, a girl who is sent to a boarding school while her father is out of the country working on a film. Unfortunately for Jennifer and the other girls in the school there is a raving psychopath wandering the grounds and butchering the students. When Jennifer meets up with entomologist Dr. John McGregor, played by the late, great, Donald Pleasance (Halloween) she learns of her great power to control insects. If she is going to survive and save the other girls in the process she'll have to learn how to use her gift to stop the killer.
Creepers is very entertaining and moves at a good clip, it's original and well acted for a horror movie. From reading the other reviews I see that this seems to be a shorter version of Argento's "Phenomena". Where Creepers runs about 82 minutes, Phenomena is 110 minutes. I haven't seen Phenomena yet but plan on it. If your a fan of Argento's or horror movies in general this movie is for you.
