“Robert The Doll” (* out of four) was a lifeless thriller supposedly based on true events set in London about a family who begin to experience scary supernatural events at their house when their son acquires a creepy doll named Robert. Yet another would-be horror movie about a killer doll but this one makes “Annabelle” or any of the “Child’s Play” sequels look like the height of terror and excitement. Being based on a true story doesn’t make it a story worth re-telling. Lock this one in your closet.
