What could have been a great horror movie was instead brought low by mediocre acting and a plot completly stolen from another horror movie that did it so much better: Ginger Snaps. If you look, each film has 2 main female stars who are inseperable, then one is possessed by an evil force (demonic for JB, werewolf for GS) while the other is trying to figure out how to help them, and in the end the good one is infected as well. While Megan Fox is hot, there is nothing in this film really worth the time spent ogling her. Pass it up for Ginger Snaps instead, same plot, better execution.
