Common Sense Note
Parents need to know that the third installment in the Twilight movie phenomenon is more mature than its predecessors but ultimately still age-appropriate for teens. As always, it's critical that parents understand that the story's central relationship is extremely intense -- almost to the point of addiction or obsession -- with Bella more than willing to forsake everything (even seeing her parents again) to turn into a vampire and join Edward for eternity. There's more vampire-on-vampire and wolf-on-vampire violence this time around; the climactic battle scene includes bloodless decapitations, dismemberments, and close-contact fighting. Compared to the first two movies, there's also quite a bit more sexuality -- with several passionate kisses and a frank discussion about virginity and first times. All of that said, like Stephenie Meyer's Twilight books, Eclipse has very little swearing and, except for one flashback scene, no drinking.
Sexual
Content
As both the books and the movies progress, there is increasingly more kissing and sexuality because Edward isn't as afraid of touching Bella. Jacob and Bella share a passionate kiss. This installment also features two unwanted kisses that end in slaps across the face. Jacob is frequently shirtless; in one scene, he warms Bella with his body (no sensitive body parts shown).
Violence
This is the most violent Twilight movie to date, with an extended battle scene between the army of newborn vampires and the Cullen/werewolf alliance. Several decapitations and dismemberments (though no blood, since vampires break like ice when they're cut in half) and a high body count overall. In one disturbing flashback, a woman is shown about to be raped (though some younger viewers may miss that this is what's happening).
Language
Less swearing than most PG-13 movies. Language includes "ass," "bad-ass," "damn," "hell," "bloodsucker," etc.
Social
Behavior
There are some positive messages in this story about love, friendship, and loyalty, but they're secondary to the overwhelming, obsessive nature of Edward and Bella's relationship and Bella's willingness to give up everything else to be with Edward. This time around, the couple does compromise on several points (when to have sex, when to "turn" Bella, whether she can stay friends with Jacob) instead of seeming to be completely led/directed by Edward.
Consumerism
Slightly less consumer product placement in this installment of the series, although Edward's car is again a Volvo SUV (XC60). The movie also has huge merchandising tie-ins with Volvo, the Lip Venom comsetics line, Mattel, Hot Topic, and more.
Drugs / Tobacco /
Alcohol
In Rosalie's flashback, her fiancé is shown drinking with several friends, all of whom are drunk.
