The movie is a perfect psychological thriller. Jack, an aspiring but failed writer undertakes the winter-caretaker duty of a hotel on the Colorado mountains. Yes, he comes with the quite dysfunctional family, through in the beginning of the movie Jack, wendy the wife and danny the kiddo play the audience, giving an atmosphere of normalcy around them. Well, slowly we see the facade falling, as Jack is showing the symptoms of a mentally ill person (hallucinations, sudden rages, depression). It is quite a watch to see how his illness develops in a terrible murderous fashion in the solitude of the hotel. Wendy's courage and Danny's apparent "psychic" powers add to the charm of the movie.
