Parents need to know that this R-rated comedy is much crasser than star Katherine Heigl's last romcom, 27 Dresses. It's heavy on sexual references and scenarios (Jell-O wrestling, vibrating underwear, etc.) and light on sweetness. The characters are stereotypes until the end, and most of the messages about dating and relationships are shallow and, frankly, sexist (i.e. women should play games and hide all traces of their true personality if they want to "land" a man). There's also lots of strong language, from swear words like "f--k" and "s--t" to body-part terms like "balls," "c--k," "p---y," and "tits."
