Strange little "Halloween" rip-off, 2 April 2000
Author: ehoshaw from Trenton, Michigan

Two young women are watching a slasher movie at the beginning of this film. A strange man sits behind one of them and stabs her through the back of her seat. We find out later that this man is a homicidal bride killer, because he was stood up at the altar years back by his bride, whom he later knifes. Now, as the police are searching for the man, he goes after pretty Amy Jensen, a nice girl who is getting married to a big jerk named Phil. Amy and her friends Joyce and Nancy are getting together with friends for the weekend and guess who crashes the party. There are a lot of bloodless, pointless murders in this one, huge plot holes in the script, a score that sounds curiously like Carpenter's in "Halloween", and a stupid twist ending. Yeah, yeah, yeah, Tom Hanks is in this, big deal. He has only a five minute part, playing a psych major. The climax in them morgue is alright, but Armand Mastroianni's direction is less than great. An average slasher film.
