Many positive messages here: The importance of loyalty and friendship; hard work leads to success; academically successful students make great athletes. Girls and boys play on the same hockey team, an admirable nod to equality in high school sports. There's even a minor plot about students wanting to change the name of the school's teams because it has a demeaning subtext. But there's also a streak of classism that fuels the film's plot; the established hockey players don't want the Ducks around because they look down on them for being from the "wrong side of the tracks."
There's bullying, but it's played for laughs; nevertheless, it's still mean-spirited. A fair amount of rough play at hockey games -- for example, a student flies through a glass wall and hits the bleachers, and students shove each other.
A boy hits on as many classmates as he can, regardless of whether they're attached or not. Teens kiss after a victorious game.
Some swearing from teenagers, including "hell" and "stupid."
REM, Pantera, the Anaheim Mighty Ducks are all mentioned. Logos for sports teams visible.
