I'm amazed so many reviewers found this thrilling or shocking, unless they've spent their whole lives in a nunnery. At the outset, the film offers so much potential but there is little build up of character or suspense and by the time things really kick off, about half-way through, you will no longer give a toss what happens to anybody. Not shocking, not harrowing, not intelligent. Less thrilling than the local weather update on TV.
