@miguelreina It had nothing to do with demonic possession. The satanic cult and paranoia were Laura's delusions because of her psychosis. David's condition seemed to be inspired by variegate porphyria, which causes abdominal pain, vomiting and skin damage. This is why his symptoms subsided everytime he drank blood.
@erebos It is true that one of the intentions of the film is that the audience doubts the sanity of the protagonist. This ambiguity about whether what we are watching is real or the product of psychological trauma is one of the interesting things about the film. But I think the story makes it clear whether or not it is a product of Laura's psychosis. Especially in the final scene. The director has also suggested it in an interview: "I wanted to keep the audience guessing all the way through wondering if Andi Matichak character was really insane or if was what she was seeing all true (...). The whole idea with the whole cult and following and stuff like that was to try to and fool the audience ". It is interesting what you say about the variegate porphyria, I didn't know that disease. I don't know if that inspired the director. Anyway, the good thing about this film is that the audience can draw their own conclusions.

Horror movie that seems to be related to demonic possession, the story unfolds in even darker and less conventional way. As a mixture of subgenres, between sects, sexual abuse and possessions, it ends up being fascinating thanks to the director's ability to create an unbreathable atmosphere. Some sequences feel implausible and the ending is not entirely convincing, but it is an outstanding terror/drama proposal.
