There are a couple things we can learn from this movie and horror in general. If the killer is a traumatized child and it is years later but we never are shown the killer, then the killer is someone we have seen in another role in the film. Stealing from the great psycho this killer is seen in bits, a hand here, a back there but never fully seen. Women's clothes are in frame sure but since we sort of know it was a boy that killed his Mom we know this is to throw us off the track. This blocking is to have a big reveal at the end of the film and chances are the killer is one of the cast who has been introduced earlier in the film. So who will it be. Well since the victims will be women we can safely go with the men that leaves it to about four people. So which of them is the secret crazed killer? The second thing we can be sure of is that each of the girls will have a trait to define them. Linda (Amy Brentano) the sorority's head is dating the football player John (Brian Charlton Wrye). Make a point at identifying the Jewish girl, Bonnie and there are several jokes she makes to make her look stupid. There is also Diana flirtatious one, Helen the cautious on,Cara is the psychic one, etc etc.
Guys had set up a whole lot of gags in the house to make it spooky, skeletons, and a coffin and some prerecorded noises. They are played to be buffoons and are played by the actors more for laughs with lines like " Eat my shorts tampon breath." One is a bit jumpy thinking the house is haunted. Played for comedy there is a whole sequence getting Larry more and more scared until he leaves. The girls for their part will be creeping around in the dark on a scavenger hunt.
The girls are blindfolded and driven to the house. Instead of using the scene to really accomplish something the director is happy to let it be filler with meaningless gabbing. So they arrive and the killer up in an upper window moves a curtain so we will know that he is there.
So you would think this is all a setup for your average slasher. Problems with the script though have the story going different directions so it never quite gets there. Early on there are visions of ghost, primarily seen by Cara but then mirrors also flash back to scenes of the past. What is frustration is those parts never really play a part in the plot. The characters don't react to the ghostly apparitions in any meaningful way. They don't really add any depth to anything we don't already know about the house's history either. The spirits don't threaten or interact in anyway with the girls so they are wasted.
The killer returns to his childhood home theme is filled with references to Psycho. The kills are not particularly graphic or suspenseful and there is no final girl. Oh and the cops in the New Jersey town are the worst cops ever, brushing off the last victims story of murder so casually you would think the production ran out of money the day they were shooting.
So in the end this is not a film that is worthy of a recommendation.
