Another well-produced horror-lite from the Screen Gems stable, they really do know how to churn these out. Not that I'm complaining, as they are usually a perfect way to pass the time, and remind me a lot of the 80's thrillerssuch as Pacific Heights and The Hand That Rocks the Cradle. Leighton Meester and Cam Gigandet give performances that are better than the hokey script, and you have to laugh when a lesbian subplot is snuck into the story, I mean you can't have a thriller about two women without one of those! A deliciously over the top final fight caps things off nicely.
