It wasn't until I checked the credits that I realized this was based off of the short film by David F. Sandberg. I knew the lights off/lights on shadow figure thing seemed familiar. While I really loved the short film, I don't necessarily agree that it needed the full length treatment. I feel like we see this a lot - capitalize off some popular internet thing that, when extended, loses some of what made it special in the first place. The short film was unsettling and creepy as it was; giving it a back story and more detail made it feel cheapened. I'm not a huge fan of "BOO!" gotcha horror movies, though; I come from a generation that was raised on the original Halloween and, for me, that is the apex of subtle, creepy, slow burn etc - everything that makes one get enveloped in a movie. When there are two many jump-atchas, it is jarring and does not make for high replay value (for me, anyway). I thought the mental asylum backstory was so played out; I feel like maybe that trope should be burned alive. We get it. Although that's kind of how I also feel about kids being creepy (or "troubled"), too. There's just so little variation in horror these days. Not all bad, though - I feel like the choice of Teresa Palmer as Maria Bello (Sophie)'s character's daughter was a fantastic choice. I not only enjoyed her performance but I feel she looks the part; she looks like a younger version of her.
