You know as much as the characters do.

Rating: 9/10 (5 January 2019)

Sandra Bullocks performance is convincing and memorable. John Malcovch and Sarah Paulson being in the film was a nice bonus as well.
I know a lot of people are complaining about the demons/entities, what are they, where did they come from, what do they want?
I for one love the fact that we don't know what they are or what they want. It puts us in the the characters shoes. They too have no idea what's going on, and that element is terrifying.
