When she hides in her little fort you can see a shadow walking around through the blankets. You can also hear something growling. I thought there was an actual monster. I wish they would of built on that. Instead it turns out that she's the monster. Maybe I missed something but what the hell was walking around in her room. They should of stuck with that concept. Once her parents came into the movie it starts to get a little strange. At times I couldn't tell the difference between the flashbacks & current scenes. I guess the story worked. I just wish they would of stuck with Stephanie alone against the monster. 5 stars
