i have watched this movie quite bemused. i am not sure whether it was attempting to be a horror gore fest in a rob zombie type affair or an exploration of real events. in either case it missed its mark. it not particularly historically accurate with characters being chopped and changed for the sake of the story. the performances were neither compelling nor bad. for me and i would have preferred a more psychological approach and this film could easily have gone down this route without spoiling the overall effect.
