Don't read too much about the movie and just watch it, else you'd lose the suspense. It's not your average so-called horror movie, that are only about some jumpscares, and lacks substance when it come to script. It is the kind of movie that keeps you gripped and wondering what's about to come. One of the best psychological horror movies I've watched. Given, I've not watched a lot of movies, the only other movie that made me feel this way was 'The Wailing'.
