Common Sense Note
Parents need to know that this romantic comedy is definitely of the crude, hard-R variety. While there are no graphic sex scenes, there are some nearly naked shots of three characters; constant discussion of sex, positions, and history; and a few mostly clothed shots of couples in bed together. Because the conversation about sex is so candid and the accompanying language so risque (the words "f--k," "s--t," "d--k" are said frequently, as are the various euphemisms for genitalia), this isn't the kind of romantic comedy that even high school-aged teens might be ready to see. Despite the raunchy humor, there's one good message in the film: that someone should love you for who you are, no matter how many romances are in your past.
Sexual
Content
Ally is shown kissing, making out, having sex with or in bed next to at least five different guys. Although there's only one sex scene (the camera only shows the couple from the waist up, and they both have tops on), there are nearly naked shots of three characters, plus several instances of rear-end nudity, a glimpse of skinny dipping (although no full frontal is shown), and lots of skin-baring lingerie and pajama shots. Other couples are shown kissing or dancing. An ex who's a gynecologist only recognizes Ally during her vaginal exam. Another ex, who's gay, propositions Ally to be his beard so he can advance politically. There are also many conversations about the pros and cons of various sexual positions, what counts as penetration, oral sex performance, "back door" action, the differences between premarital and marital sex, and other, more explicit references.
Violence
Except for Ally's various pratfalls, there's no violence.
Language
Nearly every line of dialogue has strong language, including "f--k," "s--t," "d--k," "bitch," "whore," "slut," "a--hole," "ass," "bulls--t," "oh my God," and more are all said frequently. Kids use the F-word in one scene.
Social
Behavior
The movie has one overarching positive message -- that if you're truly in love, a person's romantic past shouldn't matter as much as your future together. There are also some valuable lessons about being yourself with the people you date and some cautionary tales about what can happen if you drink too much. The central couple shows how being friends with someone is a good basis for a relationship. On the negative side, the movie reinforces the idea that men and women should be held to different standards when it comes to sexual experience.
Consumerism
Several product placements in the movie, from Marie Claire (in which the infamous "numbers" article is published) to Apple -- Macbook, iPod -- to the Honda Fit, which Ally drives in a climactic sequence.
Drugs / Tobacco /
Alcohol
Ally drinks -- a lot, either with friends or alone. She gets drunk at least three times in the movie and one of those times ends up having a one-night stand she regrets. Ally and her sister's bridesmaids do shot after shot at a bar. At a wedding reception, people are shown drinking. Ally and Colin often drink beer or wine together.
