Lights Out might just be my favorite current horror flick, right behind It Follows. I love horror movies that live up to their initial promise and precious few ever genuinely do. Lights Out is one of those precious few. The opening is creepy, and immediately offers up a really interesting concept married to some really cool visuals. The idea is simple, the monster in this movie lives in the darkness and will disappear when the lights are turned on. Such a simple idea, but a really fascinating one if used properly- and this movie uses it properly.
