I wasn't expecting the blend of found-footage cinematic storytelling. LOVE possession movies, but to work they need to have interesting characters and chilling atmosphere, luckily this doesn't disappoint with a family drama at the centre of the conflict. Good performances and production design. Most possession films these days are set in old family homes and estates, like the conjuring saga. I enjoyed the different take. Also don't google the disease, the videos are pretty frightening.
