Common Sense Note
Parents need to know that this Colin Farrell vampire movie -- a remake of the same-named 1985 cult classic -- blends comedy and horror. But despite the attempt at a lighter tone, it has plenty of vampire violence, with lots of blood, biting, stabbing, shooting, burning, and fighting. Language is likewise strong, with many uses of "f--k" and "s--t" throughout. There's no nudity, but characters are definitely thinking about sex, and there's lots of flirting and innuendo. One supporting character, an adult, may have a drinking problem, which is treated somewhat comically. So, no, this isn't Twilight -- but older teens who like their vampires with (pun intended) more bite will probably want to check it out.
Sexual
Content
Plenty of flirting and sexual innuendo (most of it dealing with a vampire's power to seduce). And Charley and Amy definitely think about having sex. They kiss, and, in one scene, Amy unsuccessfully attempts to seduce him. (Potential spoiler alert) At the end of the story, they prepare for their first sexual experience.
Violence
Though the movie's tone is slightly comic, there's still plenty of strong, vampire-related violence, including lots of blood, dead bodies, biting of necks, licking of blood, stabbing with stakes, shooting with crossbows and guns, characters being hit with cars, fighting, and explosions. Vampires burst into flame and ashes when they're killed.
Language
Strong, frequent language includes many uses of "f--k" and "s--t." Other words include "p---y," "bitch," "ass," "balls," "d--k," "jerk-off," "crap," "douchebag," "hell," "damn," "goddamn," "oh my God," and "Jesus Christ" (as an exclamation).
Social
Behavior
Buried somewhere under all the scary stuff is some commentary about being yourself: Charley tries to be "cool" for his girlfriend and avoids his old, "nerdy" friends, but he discovers that it's too much work. Likewise, when the "magician" Peter agrees to help Charley, he learns to face his problems and to think of others besides himself.
Consumerism
Two mentions of eBay, which are the setup and payoff of a joke. Ben & Jerry's ice cream and TiVo are also mentioned.
Drugs / Tobacco /
Alcohol
A supporting (adult) character drinks a great deal, almost compulsively; he even appears drunk during the final battle and takes a swig from a flask afterward -- this is all portrayed humorously. The vampire borrows a six pack of beer but doesn't drink any on screen. There's a quick joke about a teen being "on drugs."
