Just saw this. Very thought provoking throughout and quite possibly the most harrowing last quarter hour of a film I've seen for a long time. It's not often that I spend 15 minutes of a film thinking I know what could happen and praying it won't. A totally different way of looking at a subject that one might think had no new angles. I hesitate to even start this thread as I know where they often lead. Hopefully not, on this occasion.
