Looking for a feel-good movie this weekend? Something for grown-ups that addresses the everyday crises and disappointments of life, but ends with a warm, suffusing sense that all is well, and every problem, if honestly faced by a genuinely good-looking protagonist, can be solved within 120 minutes? Then this is not the movie for you. Go see Wedding Crashers instead.

The film raises and addresses profound questions about the nature of evil but doesn�t pretend to answer them.

The Exorcism of Emily Rose is the kind of movie that disturbs while it entertains. The film depicts (employing poetic license) the true story of a bright, young college student, Emily Rose (played by the gifted Jennifer Carpenter) who seemingly became possessed by six demons and was approved for exorcism by her local diocese. The exorcism was protracted, horrific, and futile. She died of malnutrition, and the priest in charge was prosecuted for criminal neglect.

The film is a courtroom drama centered on the trial, suffused with flashbacks to apparently preternatural, and profoundly disturbing events. The protagonist is the priest's lawyer (played by the ever-brilliant Laura Linney), a cynical agnostic driven by ambition, hired by a shame-faced diocese to hush the whole thing up. But the priest (portrayed by the compelling Tom Wilkinson), refuses to cop a plea�insisting that he must take the stand and "tell Emily Rose's story. That's what she wanted." The prosecutor, a dour Protestant (played with silk and steel rectitude by Campbell Scott), brings an army of expert witnesses to try to prove that Emily had a diagnosed, treatable psychiatric condition�"psychotic epilepsy"�which the priest culpably ignored in favor of exorcism. Thus the film presents forensically the clash between contemporary scientific humanism and spiritual warfare. The contest is presented impartially, with men of each tradition speaking cogently and persuasively for their points of view�including the priest. As the director said, "It really was one of my goals to present a Catholic priest as a character with dignity and respect. I think Catholics and priests are such easy fodder for stereotype and vilification. I wanted to create character you couldn't help but respect for his passion and integrity."

The film raises and addresses profound questions about the nature of evil and why God permits the suffering of the innocent�but doesn't pretend to answer them. And that's just what the filmmaker intended. Scott Derrickson, a graduate of the artsy Christian liberal arts university, Biola, calls himself an "orthodox Christian" and confesses that he's addicted to the novels of Walker Percy, and to reading and re-reading G.K. Chesterton's Orthodoxy. In fact, as Derrickson told me in an interview, Catholic screenwriting maven Barbara Nicolosi warns him, "You're just one Chesterton book away from crossing the Tiber," and becoming a Catholic. Whatever his background, Derrickson has crafted a compelling drama which sends you out of the theater feeling queasily fascinated, wondering if you need to seek some kind of protection, despite your faith or lack thereof.

I expect that this film will drive some people afflicted by unfamiliar voices and eerie occurrences to pester priests with the suggestion that they might be possessed. And the priests will do what the Church tells them to do�send these poor souls to the doctor. As the film makes clear, Church officials are extremely skeptical about such claims, insisting that every natural explanation and treatment be completely exhausted before a spiritual cause is inferred for a person's distress. When Catholics get a toothache, they're supposed to go to the dentist�not to Lourdes.

I raised with the director the possibility that the film might provoke a panic about demonic possession�as had The Exorcist, which some said inspired the delusions endured by Anneliese Michel, the real Bavarian girl upon whom "Emily Rose" is based. Derrickson admitted that it was a danger. "But as a filmmaker, I feel responsible for the effect my work would have on normal, balanced people�not on the small number of troubled souls. I mean, you can point to several serial killers who carried around the Bible. They just didn't understand it. The Bible's full of provocative, dangerous stuff."

Derrickson admits that he didn't follow the facts of the case as closely as one would in making a biopic (such as Kinsey). "I felt obliged to take this true story and do it justice by creating a thought-provoking film that caused people to think deeply about the subject of whether there's a spiritual realm. I thought this was a great way of getting into those questions. It's a work of fiction based on a real thing that happened."

The real things that happened, according to the film, are fairly disturbing�especially for a believer. Emily Rose was not a Satanist or an aspiring witch; she'd never even touched a Ouija board. Indeed, she was the pious, virginal daughter of a devoutly Catholic family�the last person who'd open herself to demonic possession. But demons seem to have kicked down the door, and tormented her for years, until Fr. Moore undertook a course of exorcisms�which failed. If a faithful and holy priest like Fr. Moore cannot expel the forces of evil from the soul of an innocent by invoking the name of Jesus... one begins to wonder: What's the point? Which side is really stronger, after all? What kind of a God permits such innocent suffering; is He sadistic, incompetent, or merely distracted? Is the Creator an overworked cosmic chef who's put one too many universes on the stove, and hasn't noticed that ours is bubbling over?

Derrickson says he wanted to raise such questions, rather than answer them. "I'm kind of a doubter by nature. That's been a big part of my spiritual journey. What I found personally compelling about this tale is that there's no easy way to resolve the questions the movie presents. There's no simple, clean-cut obvious answer. But the questions it raises are important for everybody. I'm not interested in trying to propagate my own view. It's much more about asking the right questions," he said.

The answer offered by the film's most heroic characters�Fr. Moore and Emily Rose herself�is that Emily is a "victim soul," an innocent who willingly offers to "make up what is lacking in the sufferings of Christ," for the benefit of sinners on earth. We don't like to think about saints like this�and personally, I don't recommend reading about them�but the Church has recognized quite a few, most famously St. Lidwina of Schiedam. Emily suffered, the film's heroes suggest, to prove to the world the reality of the preternatural and supernatural worlds�by showing men the devil, she would turn them to God.

Which led this viewer to ask the director if he wasn't encouraging us both to believe in God and to dislike Him? Derrickson responded: "I often find myself troubled when I think deeply about this and the nature of God. It is perplexing. But isn't that the story of the saints, the apostles themselves? People who suffered tremendously so that God's nature could be revealed to the world. That does give me questions and apprehensions about God, but I always come back to a place of comfort when I think that God Himself endured that�if you believe in the incarnation. I hope agnostics will be troubled by the spiritual possibilities the film presents, but that Christians will also be troubled into thinking about issues like this."

It remains to be seen if audiences will be challenged, troubled, and fascinated�as I was�or if they'll leave the theater unsatisfied, because the film leaves unanswered questions. Even after 9/11, and now Katrina, most moviegoers may not be interested in listening to subtle arguments about God and the existence of evil, especially on a Saturday night. I suspect they'd prefer a demon movie that delivers the "moral of the story" nicely packaged up, with a bright red bow. I can't say I blame them. Will "Emily" tap into the mass Christian audience that made The Passion of the Christ a huge success? It remains to be seen. I hope so.

'...God Himself endured that�if you believe in the incarnation.'

But there's another audience I can't excuse. Already, critics at Slate and the New York Times are complaining that this film is religious agitprop. And to them, it must seem that way, since it proposes a spiritual explanation of events as one (out of several) plausible alternatives. Compared to the films which they're accustomed to praising, that would constitute religious propaganda. If only The Exorcism of Emily Rose had (like the award-winning 1995 Dutch film Antonia's Line) presented its priest as a drooling sexual predator who molested retarded children�then it might be considered "provocative." If (as in virtually every Stephen King film) it had portrayed Christians unambiguously as dangerous fanatics, then it might qualify as "complex and penetrating," not (in the words of New York Times critic A.O. Scott) "propaganda disguised as entertainment." Scott's review says more about the narrowness of his experience and imagination than it does about the film.

As someone who does believe (reluctantly) in demonic possession and exorcism, I came out of the theater undecided about whether Emily Rose had in fact been possessed, or simply mentally ill. So did other believers I know who saw the film�not superstitious peasants, but educated people with advanced academic degrees. That's because the film is genuinely ambiguous and ambivalent. But that's not how the (mostly) secularist film reviewers for major newspapers and magazines see the film. One wonders if audiences will listen to them.
