Average horror movie at best

Rating: 6/10 (29 December 2016)

In my honest opinion, I view this movie as more of a thriller than a horror movie. There was 1 scene, maybe 2, that I really jumped while watching this movie. I have read reviews that this movie "brings back life into a dying genre," but I will definitely have to disagree that it does not. I haven't seen a good horror movie since The Conjuring 2, and after reading reviews I thought that this might be a good horror movie to watch.
Now to the plot of the movie.
I get that having sex with someone who carries "it" around results in this "it" following you, but they never explain what "it" actually is. They never explained where "it" came from or how this whole thing started. They mention that if "it" touches you - you die and then it is a trickle-down effect until it reaches person number 1. They, however, do not ever mention if this has happened, etc. The first scene in the movie is a girl dying from "it" but they never show you what happened, and then later in the movie, a boy dies because "it" (disguised as his mom) has sex with him. Literally.
I thought this movie had a lot of potential but I was wrong. It is a decent horror movie to watch but I would recommend The Conjuring series if you haven't seen those and need a good spook.
