Plenty of eyebrow-raising behavior regarding hooking up and casual sex (as well as some homophobic jokes) -- and the main character has to change her ways/who she is in order to get the guy -- but the movie does promote the idea that you can surprise yourself in good ways, and redemption is possible, but forgiveness is key. And even if you're disappointed in your family, that doesn't mean you have to cut all ties with them.
A few graphic surgery images.
Couples are shown naked (no genitals visible, but backsides shown) and appear to be having sex. The main character has a long history of hooking up/drunken one-night stands. Frequent frank, graphic discussions about sex and sexual positions. An adult woman finds out that the guy she's making out with (and about to have sex with) is only 16.
Frequent use of words including "f--k," "s--t," "a--hole," "bitch," "c--kblocker," and more.
Lots of labels/products seen, including CrossFit, Grindr, iPhone, Samsung Galaxy, Ferrari, Nike, the New York Knicks, Instagram, Skinny Cow, Minecraft.
Characters smoke weed, drink shots, and get drunk. Brief glimpses of cocaine, and in one scene, a teenager snorts something that he claims is Adderall off a woman's forehead.
