I guess i belong to the minority of people but i actually prefer slow burn/atmospheric horror films over the more conventional ones. Now with this one definitely qualifies for slow burn and i was really enjoying it up until the final act which was anticlimactic and even borderline cheesy, but the overall impact of the movie was so great that i didn't let the ending ruin it for me. Definitely one of my best horror watches of 2017 and i am curious if anyone else watched it to know how they felt about the ending.
