No matter what others have said here, this is a film that has been exceptionally well crafted, acted and photographed. It avoids many of the devices used by modern horror fims and in doing so has clealry split opinion.
If I had any criticism it would be that the film could have been longer!
Immersing ourselves into the cultural and religious landscape of those early pioneers in the American wilderness was a historical treat. The use of language gave the film an authenticty that adds to the suspense and overall story. The audience have to use their intelligence and imagination to string together some of the events, something else which added to the film's appeal for me.
This is definitely one to watch again and again. It would be even better if we could see more of the same type of film being made - the creeping uncertainty of the known unknown drives the narrative and plays on our superstitions and fears - an excellent addition to the collection of the connoisseur! Baa Baa!
