From a press release that just hit my inbox (emphases mine):
AMERICAN TEEN is the touching and hilarious Sundance hit that follows the lives of five teenagers – a jock, a popular girl, a heartthrob, the artsy girl and the geek – in one small town in Indiana through their senior year of high school. We see the insecurities, the cliques, the jealousies, the first loves and heartbreaks, and the struggle to make profound decisions about the future.
…The result is a film that goes beyond the enduring stereotypes of high school to render complex young people trying to find their way into adulthood.
No, no stereotypes here. Obviously not.
