Count me among those who do not see what the hoopla is about this film. It's an ok thriller, with some stunts, no special effects, and a few good acting performances.. It has a few shocking moments, but it also lasts 2 hours which is, in my opinion, for longer than the story could support. A word of warning: do not go into this film expecting answers to anything. It's all "left to the viewer's imagination" (the bad author's get-out-of-jail-free card that gets used and abused far too often). You'll never know what the actual threat is, nor where it came from, and the ending of the film is a bit of a let-down.
