Common Sense Note
Parents need to know that Don Jon is about a guy (Joseph Gordon-Levitt) who's addicted to porn, which means it has lots of montages from X-rated movies. No genitalia are shown, but you'll see plenty of naked breasts, graphic sex scenes (with genitals obscured), moaning, groaning, people in all sorts of positions, and implied masturbation. There's tons of swearing/crude language, too (including "f--k" and "s--t"), and one scene in which a character smokes weed. All of that said, mature viewers can still learn something from the movie, including that pornography can shape the way people/society views women and of sex -- and that it can get in the way of true intimacy.
Tons of sex throughout the movie, in all sorts of positions; although viewers don't actually see genitalia, they see everything else, especially in many clips from actual porn videos. One character masturbates many times a day; again, viewers don't see his penis, but it's clear what he's doing.
A man punches the window of a car in rage, smashing it to bits and hurting his hand. He's also an angry driver who cusses out anyone who gets in his way.
Very frequent strong language includes a ton of uses of "f--k," plus "a--hole," "s--t," "bitch," "p---y," "c--k," "t-ts," "ass," "damn," "hell," "oh my God," "goddamn," and more. Also, a slur word is used once.
It's never too late to start over, to figure yourself out, or to recover from the horrors of life (or our mind-numbing, soul-crushing proclivities). Also, pay attention to how you're being treated; what seems like love may just be selfishness.
Camaro, iPhones, Martinelli's, Coke, Diet Coke, TiVo, Budweiser, and more are shown/mentioned.
