The concept is good, but honestly Paula (the main character) is such a pathetic excuse of a final girl, more plain than white bread, bad acting and bad scripting makes watching her even worse, and somehow even though she is portrayed as a "nerd", she's stupid enough to not have any reaction when a guy she barely knows appears inside her bathroom when she is naked, whom she falls for in the last 15 minutes?
Brian was a character with the potential to be a really good killer, and Dwight is just a plain jock, but the acting of Brad Pitt makes it acceptable.
If I didn't had to watch Jill Schoelen acting like it was a high-school play for bonus points in a class she is falling for 91 minutes, it would probably be a solid movie.
