It is almost impossible to imagine that a worthy sequel to 1973’s The Exorcist could ever be made, but that hasn’t stopped several filmmakers from trying. The original film — directed by William Friedkin from a screenplay by William Peter Blatty, who also wrote the original novel — was more of a mood piece than a story. The demonic possession of a 12-year-old girl was less a conflict to be resolved than a hook on which to hang a thoughtful meditation on the tension between modern materialistic science and an ancient, even primitive, belief in a spiritual realm beyond this life. At a time when many were asking if God was dead, and if concepts such as goodness still had any meaning, Blatty and Friedkin hit audiences with a bold, shocking depiction of evil and dared them to say that this, too, was not meaningful. If there truly was such a thing as evil, then there truly must be such a thing as good, too; and if the Devil existed, then so did God.
