Parents need to know that Vacation is a sequel to/reboot of the original National Lampoon's Vacation comedies. Ed Helms stars as a grown-up Rusty Griswold, who hopes to recreate the infamous road trip his own family took when he was a teen. Like the 1983 version, this Vacation is chock full of crass humor, coarse comments, sexual references, and constant strong language. Nearly every line of dialogue includes an obscenity -- from "motherf---er," "f--k," "s--t," "a--hole," and "bulls--t" to "p---y," "d--k," and more. Violent moments/topics are played for humor (like siblings roughing each other up, a fist fight between families, a woman in a car getting killed by a truck, jokes about rape, pedophilia, incest, and more), and sexual content includes glimpses of bare breasts, scenes in which a man's large genitals are clearly outlined by his underwear, tons of crude innuendo and graphic references, and a scene of several partially nude couples waiting to have sex in public. One scene includes a mom chugging beer and then projectile vomiting while running an obstacle course.
