In fact, every second of the film has its reason.
The devil in the girl's body is not without reason, and the beautiful family is just appearance. The lively girl on the outside actually has doubts and contradictions on the inside. From the gossip magazines she read about her mother's feelings, and the time when her mother was furious on the phone and hid silently in the dark, she knew that the devil took the opportunity to invade at this time.
The story of Father Callas is more obvious, his relationship with his mother, remorse and self-blame, is also the object of demonic attack. In his connotative dream, his mother was so far away from him.
What about faith in this movie? I don't think so.
