Classic characteristic of a great movie with unusual plot that fails to have an ending. Most all newer movies share this failure. Movie goers favorites always have a fulfillment of an ending. An extra five minutes would've made this an excellent movie. Example: why not create a karma ending with the twisted torturer dying in a car crash soon after his crime?? Maybe show the woman years later getting skin graft surgeries and managing to lead a normal life? Maybe the woman could become a Dexter like character so damaged from her ordeal that revenge can never be satiated. Maybe the criminal cop could be brought to trial. Soooo many endings, just finish it!!!
