I think that the other review of this film is a bit unfair. Yes it is a quiet movie which moves with a very deliberate pace. No there is not a huge monster nor do we see it overly much. The important thing in kind of indie horror film is to establish tension then retain and gain it. The film was quite effective there. There are a number of moments which are very uncomfortable indeed in this film. By not showing too much of the creature they were using the "Cat People" dodge which is that if you don't have the money or resources for a big scary beast then let the audience imagine it. If they had shown something one wonders if the prior reviewer would have trashed them for that as well.
