The movie shows that growing up is an often-painful process. That said, the boys' friendship is a powerful force in their lives, and the movie has a strong nostalgic appeal. Themes include curiosity, teamwork, and perseverance.
A dead body is shown; references to other violent acts (including a father hurting his son and another dad shooting a gun). Some peril (a train approaching while boys on the tracks) and threats. Scuffling/wrestling.
Innuendo (references to masturbation, getting laid) and crude jokes. The boys are curious about the opposite sex and discuss girls in a crude but age-appropriate way.
Many uses of "f--k," plus "s--t," "a--hole," "t-ts," "d--k," and more, almost all by teen boys.
References to Winston's cigarettes, cherry PEZ, and Fruit of the Loom underwear.
Underage kids drink and smoke; a teen drives while drinking.
