“Behind You” (** out of four) was a hokey supernatural horror thriller about two sisters (Addy Miller and Elizabeth Birkner) who find a hidden mirror in the basement of their aunt’s house and this (naturally) unlocks an evil force which leads to the house being haunted and their lives being threatened. Far from the worst of this genre and does feature good-looking cinematography by Benjamin Allred and some scares but at the end of the day- it’s a story you’ve seen numerous times already in the past. Viewers may want to leave this “behind” them and re-watch any one of the “Insidious” or “Sinister” movies again.
