Common Sense Note
Parents need to know that some releases of this movie carry the PG-13 rating, others a PG. It's pretty mild for its type nonetheless. There is drug humor and a few sexual references and modest swearing. Reckless behavior -- on the ski slopes and drag racing in streets -- is glorified. Queasiest factor for most viewers might be the repeated depiction of (unsuccessful) teen suicide as gag pratfalls.
Brief talk/flashback about Lane losing his virginity to Beth (it's never clear whether or not it happened successfully) and condom use. Off-color confusion of words "testicles" for "tentacles" and "sex" for "sax" (as in saxophone). Visual joke in which a girl suddenly gets her clothes torn off down to bra and panties.
Reckless driving and car collisions, spills on the ski slopes, and one character beaten up (offscreen) by school athletes.
Some use of "s--t," "ass," and "damn."
Nobody here is very deep, and the hero's repeated attempts at suicide, though (half-heartedly) discouraged, are basically joke setups. "True" love, that is romance not based on who is the better, more popular guy/girl in homeroom, does win out at the end. Characterizations lean towards stereotypes (nerds, jocks, fatties, car-crazy Asians), but there's one girl who goes against the grain by being an ace mechanic and baseball fan, not a shallow blonde -- but she's emphatically not American, so go figure.
Coca-Cola and Perrier labels rather obnoxiously thrust into foregrounds. Car models and the names of several winter-sports-gear product lines are evident.
Drugs / Tobacco /
Smoking for gag effect (it causes an explosion). One character talks enthusiastically about drugs, at one point pretending that a snow-covered mountain is pure cocaine (snorting the snow to make his point). Reference to drinking and moonshine whiskey.
