Well, the premises did sound like something we've all heard of before, but the way the plot unravels actually really makes it worth your while. If you pay attention you'll notice how clues are carefully placed throughout the film and how everything falls back in to place. As I watched it I became more and more interested in the characters and their stories, and the atmosphere created by the sound design and the cinematography enveloped me and made me "believe"... I am not sure this is film for all audiences, I mean that - differently from most thrillers, this is a film for mainly adult audiences who are willing to think as they watch a film. The look of the film is great and the acting is, for the most part, amazing. I enjoyed it and would watch a second time.
