But if the film, like Derrickson's The Exorcism of Emily Rose before it, isn't some didactic shouting match between religious and secularist forces, it shouts in other ways—mostly as an unrefined litany of mansplaining which borrows more than a few notes from the granddaddy of all exorcism movies.
Scott Derrickson’s The Exorcism of Emily Rose took a forensic approach, blending a possession/exorcism story with courtroom drama.
His latest feature, "Deliver Us from Evil," also has more to say, but the problem is that the very same themes revolving around faith, religion and the darker corners of the supernatural were explored with far greater eloquence and depth in 2005's " The Exorcism of Emily Rose ."
Its police procedural twist aside, “Deliver Us From Evil” is basically the garden-variety possession/exorcism flick — not unlike other alleged true stories such as “The Exorcist,” “The Amityville Horror,” “An American Haunting,” “The Exorcism of Emily Rose,” “The Haunting in Connecticut,” “The Possession,” “The Conjuring” et al.
It took Derrickson some time to establish credibility as a horror filmmaker—he had a minor hit with 2005’s similarly themed The Exorcism of Emily Rose and made a lot of money on a small budget with the genuinely unsettling Sinister, starring Ethan Hawke—but with the support of uber-producer Jerry Bruckheimer, Derrickson’s dedication finally got the film made, though it hardly seems worth the trouble.
