“The Mannequin” (*1/2 out of four) was an unbearable horror thriller about a stylist’s assistant (Isabella Gomez) who investigates her sister’s death in a historic L.A. building and soon uncovers the spirit of a ghost in the form of a mannequin which is dismembering and mutilating victims in the area. Good production values can’t enrich this tired and tiresome material. Title is fittingly appropriate in some ways because film never comes to life. Byetheway- this is not a remake or related to the 1987 comedy cult classic of the same name.
