I enjoyed this. In my opinion it would have been so much better if they didn't include the stupid monster design of the creature or the pulling off of faces. It should have been left just with creepy people smiling and that's it. I really liked the whole psychology around it, those are my favourite horrors. The ones where their mind is playing tricks, is it real or in their head. I really liked the concept and the acting was top notch. I like that it isn't a happy ending.
