Don't Knock Twice is for me one of the biggest surprises of the year 2016. I do not watch many movies under the Drama category, but this was great and now I am bigger fan of movies of this kind. It's probably the most known Fantasy movie and it's really entertaining. Anyway, Horror may boast of one of the biggest numbers of good movies. 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.
