Common Sense Note
Parents need to know that this is a review of the PG-13-rated movie and not the unrated DVD version. This horror film, while relatively bloodless, is still totally frightening (as in NOT for younger kids). It's full of freaky, scary stuff like monsters, creatures, and demons. Since the evil entity in the movie can jump from body to body, much of the violence in the film involves un-possessed people lashing out at possessed victims -- including children. There's also lots of talk about abstract, monster-related theological issues (i.e. can a Jewish rite of exorcism protect a non-believer?). A subplot about a Holocaust survivor leads to imagery of Nazi death camps and medical experiments. Because the film's plot revolves around a stillborn twin, there's also disturbing imagery involving pregnancy, birth, and infancy that's used to create shock and horror. Characters also drink, swear, and get intimate (though nothing too sensitive is shown).
Sexual
Content
A couple (young, but college-aged) kisses and cuddles, presumably after making love. Discussion of "wood" as a indicator of arousal. Some images of the female lead character in nightshirt and panties and a waist-up, from-the-back shot of her showering. A babysitter is asked if the husband and wife she's working for have "porn," with a brief discussion of hypothetical masturbation. Sexual activity is shown to have clear consequences.
Violence
Several scenes involve violence against -- or by -- children possessed by supernatural entities or supernatural entities in the form of children. Stabbings, bludgeonings, beatings, and other forms of violence. Some blood, though less than in many other horror films -- but there are many mutilated bodies, and some graphic images of contorted/dislocated limbs. Constant horror-film imagery, including swarms of insects, misshapen supernaturally influenced beings, howling monstrosities whose entire face is a fanged maw, and more. A child is hit by a car (though unharmed thanks to dark forces); later, the same child stabs a character to death. A plot point revolves around the death of an infant. The finale involves lots of supernatural violence -- people and objects being hurled about by psychic force -- and some violence committed by people possessed by that force. Characters are chased and threatened by scary monsters. Some World War II concentration camp imagery, including medical experiments on children; other medical imagery includes an eye examination.
Language
Some instances of strong language, including one "f--k," "s--t," and "bitch." "Retard" is used as an insult.
Social
Behavior
Extensive discussion of mystical and demonic elements of Christianity and Judaism. Several scenes are set in a home for the elderly, with discussion of the frailties that can come with age. Discussions of the Holocaust. Extensive imagery involving birth and pregnancy and its complications, including a fetus in a jar (which is later shattered). Discussions of Alzheimer's (referred to as "old-timers"), clinical depression, and genetic abnormalities.
Consumerism
Some brands are visible on-screen or mentioned in dialogue, including Cosmopolitan magazine, Red Bull energy drink, and Xanax.
Drugs / Tobacco /
Alcohol
Characters drink liquor at a club and talk about being drunk; one character notes of the other's stressed-out state that "I would just take one of my mom's Xanax and call it a day." A character is seen leading some sort of 12-step group, although for what, exactly, viewers are never told.
