This movie was terrifying and suspenseful right from the beginning and didn't end until the shocking twist ending. I didn't talk my eyes off the screen until it was over. The characters were unbelievably authentic, from their first scene to the end. The bad guy was evil and twisted from the get go, as good a performance as Robert De Niro in Cape Fear. The girl was genuinely terrified right from her first inkling of her situation. She adeptly displayed a combination of loyalty to her friend, fear, heroism and strength. The ending was a spectacular and surprising twist. A thinking movie leaving you pondering what human values have become. A great movie, well worth watching. Hopefully more will come from this great new director, the screenplay writers and these actors.
