Horror movie fans may find The Exorcism of Emily Rose too tame. Images of a possessed girl munching bugs, twitching her limbs and punching her dad are tacky rip-offs from the 1973 horror classic The Exorcist. Director Scott Derrickson (Hellraiser: Inferno) has taken a great deal of artistic license with the controversial material, but the basic theme of faith versus science remains intact. The film is about a priest (Tom Wilkinson) who is put on trial after a young girl - believed to have been possessed by at least six demons - dies following an exorcism ritual. Defending the priest is a rising lawyer (Laura Linney), whose agnostic stance is gradually swayed by a series of ominous events that occur during the trial. Was the incident a true demonic possession or a tragedy of blind religious faith? The film hints at the former, as Derrickson fails to give equal weight to both sides of the story. By siding with the priest and exaggerating the ominous and inexplicable details, the film is very effective as religious propaganda, but is shamelessly imbalanced as an inquiry into the limitations of religion and science. But the fact that the movie is based on a real story will definitely send a chill up your spine. VERDICT: GO TO THE MOVIES
