Wonderful film. It's not for everyone, it's honestly not even for ME, but it does whatever it does well.
!! spoilers ahead !!
I was entirely unable to be home alone for a few weeks after watching this. I still have to leave my curtains open to know my window is still there, I even removed the door on my closet. The entire point of the film is suspense and unease, that feeling that something is so, so horrifically *wrong*. Seeing it partially through the eyes of children makes it so much more disturbing. I highly recommend this film to anyone who wants something different than the standard jump scares and bad plot of modern horror. It left me paranoid, panicked, and throwing up- and that's a good horror movie in my book.
