“Don’t Sleep” (*1/2 out of four) was a listless horror thriller that will likely put you to sleep about two young lovers (Dominic Sherwood and Drea de Matteo) who move into a cottage together and are soon confronted by the horrors of their forgotten childhood involving his vindictive doctor (Cary Elwes). Umpteenth rip-off of “The Exorcist”, “The Shining”, and (naturally) “Paranormal Activity” offers no originality and hardly any scares. “Don’t Watch” would be a better title for this misfire.
