Before I heard of this film, I would have laughed at the idea that Vince Vaughn and JLo would be the leads in one of the best thrillers I would come to watch, but sure enough it happened. The visuals alone make this a worthwhile watch. You'll never see a thriller that looks quite like this one. A lot of art-inspired scenery makes for hauntingly beautiful yet uncomfortably suspenseful scenes. The idea of sympathy toward a mad killer is somewhat unique as well. The whole thing is simply very original, suspenseful, and interesting. Top notch thriller movie, and in my opinion very underrated (this is the first time in a while that my own rating does not match average critic and audience ratings).
