8 Possession Horror Movies That Broke All The Rules

Across the past decade or so, there has been a slew of possession movies that have used the formula to present stories that are really about mental illness, disease or identity. The likes of The Babadook and The Taking of Deborah Logan are just two examples that blended heavy, real-life subjects with the thrills of a ghost story successfully, but Relic is perhaps the most subversive of the bunch.

Part possession movie, part haunted house scare fest, the flick sees mother and daughter duo Kay and Sam moving in with Kay's mother Edna, whose dementia is gradually worsening.

However, the pair find themselves trapped in the house and haunted by Edna, who is being taken over from the inside by some kind of supernatural mold.

The twist here is how there's no explosive finale, no grand exorcism, or anything like that. Contaraily, the finale sees the family reunited and instead of running from the force that's been chasing them for the whole film, finally accepting it as part of their lives.
