This movies does start out a little slow but speeds up later. I sometimes wondered if I was watching a thriller or a horror movie with all the jump out scenes. Naomi Watts plays a child psychiatrist who recently lost her husband and her son became a vegetable. When one of her patience shows up in the middle of the night and then disappears a state-wide man hunt is initiated due to the giant snow storm headed in. With all the twists and turns this movie does have its moments. I diffidently could not have guessed how it would have ended. I thought the ending was very well thought out and interesting but I don’t want to give too much away. I give Shut In 4 out of 5 stars and I highly recommend it to those who love thrillers.
