When a bunch of yahooing snowboarders snake down perilous peaks, you'll be like, ''Extreme, dude!'' The generic techno tunes will make you shout ''Heigh-ho, Extremeness!'' When a plot tardily kicks in as the boarders stumble across a Bosnian war criminal in hiding, you'll ask, ''Hey, who ordered the plate of Extreme?'' And if you've ever seen even one Mountain Dew ad, you'll be extremely bored.
