Common Sense Note
Parents need to know that teens may be drawn to this horror movie by co-star Chace Crawford, who's part of the cast of Gossip Girl. There's some violent, scary stuff, but it's also mostly bloodless (particularly when compared to movies like the Saw franchise) -- more blood is seen from the lead character's stress-induced nosebleeds than from any of the movie's stabbings, assaults, and murders. The film includes a lot of religious imagery and plot points -- characters read Paradise Lost and the Bible, the lead character is baptized in an effort to remove the diabolical influences she's experiencing, and more.
Some kissing; cleavage is revealed; the lead character strips down to her bra while changing.
A man drives dangerously as part of a suicide attempt (with another passenger in the car); scuffling and fights; a girl's arm is sprained in a fight; a woman falls over a railing to her death, landing on a knife she was brandishing. An attempted murder by drowning. Multiple stabbings, with some blood -- including some self-inflicted wounds. A scary, mutilated ghoul is on screen for a split-second. Some hospital/surgical imagery.
Some harsh language, including multiple uses of "s--t," "hell," "damn," and one non-sexual use of "f--king."
The lead character is unknowingly part of a Satanist plot to find a host body for the Devil. A supporting character speaks of her own relationship with Jesus Christ, and the lead character goes to her for salvation when the plans for her life become known to her. Some discussion of the nature of madness.
Only one brand (Ford, on a car's hood) visible on screen.
Drugs / Tobacco /
A character is seen extinguishing a cigarette, but not smoking it; teens drink what is presumably alcohol at a party, despite being underage.
