“You Shall Not Sleep Tonight” (*1/2 out of four) was a morbid psychological thriller likely to put viewers to sleep about a young boy (Milo Burgess-Webb) haunted by nightmares of a frightening monster inside his closet and his dedicated father (Agustin Olcese) helps him to fight his fears and also fight the monster. Clunky horror storry feels like reheated Guillermo del Toro (“Pans Labyrinth” in particular) and maybe a little of early Spielberg (“E.T.”). Good performance from young Webb is film’s only real merit.
