Parents need to know that Booksmart is a delightfully intelligent, raucously funny coming-of-age comedy about two responsible high school girls (Beanie Feldstein and Kaitlyn Dever) who, on the last day of senior year, decide to go to a party. The movie has the potential to become a classic of the genre, but the mature material gears it toward older teens and adults. Teens inadvertently take a hallucinogenic drug and go on a "trip," and there's teen drinking, pot smoking, and other brief drug use. Language is extremely strong and nearly constant, with many uses of "f--k" "s--t," "bitch," and more. While there's no graphic nudity, audio from a porn video is heard, teen girls start to have sex in a bathroom, and there's pretty explicit sex talk, banter, and innuendo, including mentions of masturbation, "scissoring," sex dungeons, oral sex, same-sex experiences, manual stimulation, and more. An animated sequence includes naked Barbie dolls. A delivery driver shows teen girls the gun he has in his glove compartment, but violence isn't an issue otherwise. Amid all of the iffy behavior are strong messages about what it means to be a good friend, and a lot of how the two main characters talk to each other and support each other is framed around being confident, smart, and body positive.
