The movie celebrates unconventional girls who may not be interested in traditionally female hobbies and are longing to find other ways to express themselves. Some of the "toughness" is heavy-handed posturing, but a lot of it is played for laughs. Even the "villain" isn't necessarily a bad person -- she's just a tough girl looking to win. As typical of this genre, parents and their kids start off completely not understanding each other but find common ground through communication and acceptance. A mentor reminds the main character to appreciate her family. On the downside, there's some stereotypical treatment of small-town life.
Positive Role Models & Representations
Roller derby is very aggressive, and the film showcases plenty of bruising, bone-crunching action. Characters are elbowed, kicked, and pushed around, and they sometimes end up bloodied. There's also some outright fighting, and trash talk is a common occurrence on the track.
Teens kiss and make out, and one couple goes all the way -- no sensitive body parts are shown, but you see them stripping to their skivvies underwater in a swimming pool and later holding each other out of the water (bare shoulders showing). The girl later discusses the experience euphemistcally with her mother. References to penis size.
Fairly frequent use of language like "jackass," "hell," "s--t," "bitch," "screw," ass," "balls," and "goddammit." There's also one use of "f--k," and a character gives someone the finger.
Brands/logos seen on screen include Google, Coleman, Zenith, and Barbie -- though all play fairly minor roles.
Ease of Play
Some underage drinking. A teen girl gets drunk at a party and makes out with a random guy before throwing up; later, a teen is arrested after being caught with a drink in public. One character (not a teen) does a kegstand. A mother hides her smoking from her daughter. A father drinks beer while watching sports and lets his teen daughter take a (big) sip. A mother mistakes a marijuana bong for a vase.
