Common Sense Note
Parents need to know that the second installment in this hit time-travel trilogy is slightly more "PG-13" than "PG." You'll find more language (including "s--t" and "a--hole"), sexual references (including jokes about breast implants and allusions to adultery and threesomes), and negative role models (the plot includes a lot of Biff in all three time periods) than in the first movie, so it may be an iffy pick for early-elementary-aged kids. But for mature older tweens -- or kids who've already enjoyed the original -- the visuals about the movie's "future" and the physical comedy will entertain, even if the time-travel twists can get confusing.
Sexual
Content
More sexual innuendo than in the original. In addition to a couple of quick kisses between Marty and his girlfriend, there are references to breast implants and size, infidelity and unwanted advances. In one scene, a married male character is shown with his arms draped around two swimsuit-clad groupies in a hot tub.
Violence
A character is seen shot by terrorists but escapes injury. A bully makes several threats. Some dark/ominous imagery.
Language
Words not usually associated with PG movies are used a few times, including "s--t," "bitch," and "a--hole." Other language includes "hell," "stupid," "suckers," "butthead," and "loser."
Social
Behavior
One of the movie's pervasive messages is that if you could change any one thing, it should obviously be to make yourself rich. That said, Marty's time travel demonstrates the importance of family (whereas Biff's desire for time travel is rooted solely in greed and materialism). The movie also has a strong theme about not letting what other people think of you bother you.
Consumerism
Product placements include Nike, Pepsi, Texaco, Black & Decker, and AT&T, all of which are sort of poked fun at, since the movie is set in the once-distant future. And, of course, there's the famous DeLorean.
Drugs / Tobacco /
Alcohol
Marty's mother obviously likes to drink, and references are made to her possibly being a "drunk." Biff is shown with a drink in his hand.
