I bought this film months ago and delayed watching it as I thought it was simply the psychological effect on a family of being stalked by a malignant and possibly violent man - how wrong I was. This is a really good plot-twister where Sam Shepard and Michael C Hall act their socks off to produce an unexpected 'buddy movie'. To say any more would give away plot twists, but the build up to fear in the first half hour was superb - what happened in the next hour or so was so unexpected - A good film to watch with the lights off and perhaps a beer or two to sup as the story develops! Worth at least 7 stars, possibly 8!
