Common Sense Note
Parents need to know that while teens will be clamoring to see this darkly funny horror movie -- which stars Transformers' Megan Fox and was written by Juno's Diablo Cody -- it's full of gory demonic violence, sex (including partial nudity, same-sex kissing, and a pervasive tone of sex as a game, a competition, and even a prelude to murder), constant strong language (from "f--k" to "s--t" and more), teen drinking, and more. Teens who watch expecting an offbeat screwball comedy like Juno will be in for a huge shock. Parents also need to know that this review is for the rated version of the film.
Lots of sex. Teens have consensual, safe sex; male and female nudity, reference to condom use. Nude female buttocks. Two young women make out in an extended scene. Plenty of naughty talk about sex and virginity -- "I'm not even a backdoor virgin," for example, and much more. Talk of flashing breasts to get served alcohol.
Gory violence: A young woman is stabbed to death as part of a satanic ritual; several people are devoured in bloody fashion by a demon that has possessed a young woman, with shredding of flesh, blood, etc. A fire at a bar kills several people; also stabbings, punches, kicks, and self-mutilation. Dead bodies are seen in crime-scene footage.
Constant strong language, including (but in no way limited to) "f--k," "motherf--ker," "s--t," "hell," "ass," "t-ts," "damn," "dick," "dillhole," "goddamn," "retarded," "porking," and much, much more.
Considering that one character becomes a demonic killing machine and another goes on a killing rampage to avenge her, it's hard to find any positive messages here.
Many products/brands are mentioned by name -- including (but not limited to) Vagisil, Monastat, MySpace, Chevy, The Cheesecake Factory, and many more -- but more as a way to make the dialogue sound cool/up-to-date than in a particularly promotional/salesy manner.
Drugs / Tobacco /
Teens drink hard liquor and beer, sometimes to excess; characters smoke cigarettes; references to peyote; cocaine use is implied in photographs.
