My favorite movie from year 2017. I don't watch too many Horror movies, but this one was amazing. The movies industry, can't really boast with a large number of better Mystery films. The film is interesting, it does not get boring, it does not get long and although it is not an original production, good acting and skilfully written script make it worth watching. I've been a big fan of such cinema for some time. It's a movie for everyone, I'm sure you'll like it after watching.
