For those fans who love church and exorcism horror, Freevee has an excellent British TV series about a priest/exorcist. The series is called Apparitions. It only has six episodes but they are incredibly written and acted.
Apparitions tells the story of Father Thomas and his battles with demons and the possessed. These stories are told intelligently, so don't expect a Buffy the Vampire Slayer monster of the week. These stories are incredibly psychological. This is a series I will highly recommend if you are looking for something superior to The Pope's Exorcist...
