My daughter started watching this movie while I was in the next room working on a project on my computer. She asked me to come watch with her when I got done. I continued working when suddenly I heard that dark violin humming sound and I was immediately drawn in. I was not even watching the movie yet. The music itself will startle and shake you. I stayed up all night and watched till the end. It reminded me of project terror/twilight zone nights with my family when I was little. I have not felt that way about a movie in forever. It was soooo good!!!
