Common Sense Note
Parents need to know that this violent (yet curiously dull) slasher-style teen horror film -- which is a loose remake of the identically named 1980 Jamie Lee Curtis movie -- includes a constant stream of stabbings, stranglings, and other murders, all of which are committed without craft, tension, or any subtlety whatsoever. It's just a string of killings and gory bloodshed. There's also some discussion of sex and sexuality, references to underage drinking, and strong language ("s--t").
Sexual
Content
Cleavage discussed and on display; characters talk about "alone time," "looking sexy," and "getting laid." The protagonist's stalker is clearly motivated by romantic/sexual pathology. A group of older men invite female teens up to their hotel rooms; the young women laugh it off. On-screen sexuality is limited to light making out in the context of committed relationships.
Violence
A total of 13 murders, mostly committed with a knife (although there are some stranglings and a shooting as well, plus scuffling, someone's face getting smashed into a mirror, and kicks to the face). Many of the murders occur off screen, and viewers never see a knife cutting or stabbing into flesh, but there's plenty of spurting blood and shots of bloody murder weapons. Several corpses with visible bloody stab wounds or lying in pools of blood are shown.
Language
Language includes "goddamn," "s--t," "damn," "hell," and "bitch."
Social
Behavior
Some discussion of class; a rival for prom queen notes that "I just want Crissy to know she can't buy everything." Crissy is also referred to as a "rich bitch." And then there are all the killings...
Consumerism
Only one logo visible -- Jones Soda -- although one character offers another "a Midol" for cramps.
Drugs / Tobacco /
Alcohol
A group of teens hoists a beer keg into the hotel; another underage attendee is busted trying to smuggle a bottle into the prom. A third character pours alcohol from a flask into his soda. The lead character has been taking Klonpin for anxiety, but at the start of the film has not been taking it for a week: "I don't want to feel numb ... I should be a little bit nervous on prom night, right?" Later, she does take one, albeit with good reason.
