Saw this recently on a DVD. Having enjoyed Flanagans Occulus n Hush, (yet to c the sequel of Ouija) i was excited to see this. The film which is based on Kings novel is about a couple trying to save their marriage by spending time at a remote house. Thru trailer itself, v come to know that after handcuffing the wife on the bed, the husband suffers a heart attack leaving the wife tied up with no help near at all. 127 hours scenario? To make matters worse, there is a hungry dog on the prowl. The wife later starts hallucinating n she goes thru the mental trauma remembering her dark past.The film succeeded in capturing the creepiness of isolation and immobilization n the growing dread. The good thing about Flanagan is that he can manage to build up tension n suspense in spite of minimum characters n action. Hush was the best example. This movie is more of a psychological survival drama with elements of horror.
