this is a very dark movie and somewhat better than the average asylum film. it was a lot better than i thought it would be and is a combination of a psychological thriller and a horror film. the voice on the telephone is really creepy  this voice without a face and this unknown and threatening voice works really well in the film and since we never see the killer face is left to the imagination of the spectator. the action and suspense never decay and after the first half of the film and it becomes vertiginous while there is not much gore in this film and just enough to serve the story and also the director does a good job at holding your attention. i gave this movie a positive because some clichés.
