ohhhh interesting theory. That makes sense as a thematic standpoint- I was having trouble grasping what the genre was really trying to be, which left me confused as a whole. The miniatures never really made their way into the storyline at all, and I’m very unsure about how the possession was happening. Was what we saw mostly Annie’s DID? Why did she light on fire the first time she burned the book and then when she threw it in later he burned? And that THAT was what finally possessed her for final form to stalk poor Peter? We can assume all of the family were just pawns in the ritual, so then what was the point of everything?
What the film did right is keep us engaged and suspended in anticipation the entire time. Not too many cheap jump scares. I just left having more unanswered questions than not. Sorta like It Comes At Night, except at least that one made sense as a theme of the thing we fear is fear itself. This one? Uhhhhhh hail Satan?
