I just saw this last night - a very cool watch! It's not the scariest movie ever, but, unlike alot of thrillers, it affected me deeply and took me on an interesting journey. It was very well cast and directted and the pace really worked. I love films that use the kind of eery, tense atmosphere that builds and builds as you anticipate the ending! Plus, the slow, artful reveal of the truth during Jenny's personal investigation and the cool plot twists kept me totally into it till the great rollercoaster ending! A definite thumbs up!
