Worth watching for entertainment value if you like fictional accounts of an actual person who was the Vatican's exorcist. The underlying theme is that the atrocities carried out over years by the Catholic church (the crusades, the Spanish inquisition, etc.) happened because of demonic possession of Catholic clergy. The moral of the story is that you need the secret Voodoo of the Catholic church to dispel the demons in your life. Give me a break. A not-so-finely crafted piece of Catholic propaganda IMO.
