Went to see this today and had low expectations that were pretty much met. I found it anemic, dull and tedious at times, it seemed more like a teen drama that you'd see on television than an actual film. The interactions between the main characters were unbelievable and unrealistic to the point of being laughable. There were long sequences were it seemed like nothing was happening and I kept waiting for the action to build but there really was no suspense to speak of. It's very much a watered down version of films like Single White Female, Swimfan, The Crush and The Hand That Rocks The Cradle, all of which were far superior. It really offers nothing new to the genre and was quite derivative. The only bright spot was Minka Kelly who can really light up the screen, incredibly beautiful and charismatic. It might be worth a rental in my opinion, but don't expect much.
