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.
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).
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).
Less swearing than most PG-13 movies. Language includes "ass," "bad-ass," "damn," "hell," "bloodsucker," etc.
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.
Drinking, Drugs & Smoking
In Rosalie's flashback, her fiancé is shown drinking with several friends, all of whom are drunk.
