Personally, I really liked the movie, loved it even. I agree that it doesn't resemble the trailers, but I'm okay with that. The cinematography was gorgeous! I felt amazingly creeped out! I felt like I was in some sort of escape room!
I am not a religious person, and after viewing the movie, I already know there will be offended parties. (That is something I will not touch on.)
If you're planning on watching this movie, have zero expectations (other than the possibility of being offended if you're religiously aligned).
