Common Sense Note
Parents need to know that this final installment in the Back to the Future trilogy is, like its predecessors, a PG film with a tad more language than usual. But there's actually slightly less innuendo and a lot less bully-related violence in this one than in Part II. The coarsest language includes "bitch," "assh--e," and "s--t," with several insults and synonyms for "coward" thrown in on a more regular basis. Although there's romance, it's very chaste except for two kisses and one off-color reference to what a woman could do that's worth $80 to settle a debt. All of the violence involves guns and fists, and in one brief scene it looks like Marty is going to be hanged, but no one dies, and it's all kept rather comical, even when a huge group of horse-mounted Indians are riding with guns and arrows. Unlike in the first two movies, in this one Doc Brown learns love is even more important than his rules for time travel.
Sexual
Content
A couple of kisses but mostly there's a lot of longing looks between Doc and his love interest. In one scene a man makes a reference about what a woman "could do worth $80," which a child may not understand but clearly alludes to sex. Marty and his girlfriend Jennifer also exchange a couple of heated kisses.
Violence
Violence is all Wild West-style: there are barroom brawls, a shoot-out at dawn (well, 8 AM) and other old West violence, none of it particularly nasty. The Biff ancestor is aggressive and likes to push Marty and his ancestor around -- shooting at Marty's feet. When he first arrives in the Wild West, Marty encounters a group of horse-mounted Indians riding toward him with guns and arrows. In one brief scene, Marty is shown with a rope around his neck, as if he's about to be hanged -- until he's saved.
Language
Some stronger words than usually heard in PG movies: "bitch," "assh--e," and "s--t," as well as mild insults like "damn you to hell," "chicken," "yellow," "coward," "lily livered," "gutter trash," and more.
Social
Behavior
One of the most important messages in this movie is letting go of words that rile you up -- not taking the bait when bullies try to demean you. It's good for kids to learn that words, although they hurt, don't need to catalyze you to do self-destructive things. Marty finally learns this lesson at the very end of the film. Doc's decision also shows that in the end he values love over all else.
Consumerism
Marty wears Nike sneakers, the discontinued sports car the DeLorean is of central importance.
Drugs / Tobacco /
Alcohol
There's drinking in the town saloon that is shown a few times. Only men are shown with drinks in hand.
