This movie isn't very scary, but it's never boring. The basement and the climax have tension, but the rest of the movie just isn't scary. In fact, there are more funny moments than scary ones: some girls at the party gush over how cute an average guy is when he gives the goofiest, cheesiest smile imaginable; Mrs. Slater tries to be intimidating, but the acting just comes off as cheesy.
There are some things that are confusing: the prank scene and Eric. When Vicki points the gun at Mrs. Slater, the girls think it isn't loaded because Vicki said it wouldn't be. She then points it at a lamp post and shoots it, breaking the glass. A friend comes up to stop her, and Vicki shoots her in the leg. They then reveal that it was a prank, and Vicki wasn't really shot. Then the gun goes off and Vicki accidentally shoots Mrs. Slater for real. What was really in her gun? Blanks, bullets, or a mix? If Vicki shot her friend with a blank, then where did the fake blood come from? And how did the lamp break if she was using blanks? For the lamp to break, she had to have been using at least some real bullets, but the movie never really explains how all this happened. The second confusing thing is Eric. The doctor says Eric died at birth and Mrs. Slater just pretends that Eric lives to make herself feel better. But during the climax, Katie fights the killer, who appears to be a man, and Ms. Slater seems to have been dead the whole time. If this were true, then how would the doctor have not realized the baby was alive? The baby he delivered was either already dead or died soon after, certainly before Mrs. Slater woke up. So assuming she got her baby back after for a funeral, the doctor should have realized the baby was alive. If this is what happened, the movie didn't make the twist very clear.
