It is OK movie. Nothing special, viewing it as a whole, but it does grab your attention most of the time. The title of the movie may give you the impression that it is a horror movie, but it is a drama with elements of thriller. Sarah was very good in the movie. I don't know the names of the 'brothers' but for what they acted, it was good. The twist or the changing of the roles is clever, but then the blood connection makes no sense to me - that is, if the other brother consciously decided to switch the roles. I did not like the very ending with the hands of the 'spirit' helping her tie the chain... All in all, six from me.
