Shane and Lizzie are sisters whose parents divorced. Shane went with her mother to California, and she cares about nature, she refuses to eat meat, and she practices yoga. Lizzie stayed with her father in the Washington, D.C., area, and she is intelligent, politically involved, driven to succeed, and carries a cell phone everywhere. Both girls want to change the world, in their own way.
Shane and the others wonder why there are only seven contestants when eight is normal. It seems Lizzie is late (unusual for her, actually), and when she finally does show up, Shane is not happy. Both girls come close to quitting.
The show is part 'Survivor' and part 'Fear Factor'. The eight young people are divided into two teams. Since the show is being filmed in Mexico, the teams are the Aztecs and the Mayans. Both sisters end up on the Mayan team.
As is often true in Disney movies, the ones you don't want to win get ahead in the competition, and you begin to wonder about the team you support, who are subjected to humiliation whenever they fail. But both Shane and Lizzie contribute unique abilities to their team, so there is a chance.
Though I have seen only clips of reality shows, I thought the 'Challenge' program seemed very realistic in its presentation, as if I was watching that show rather than a movie about it. The acting performances were stereotypical for the most part. But I especially enjoyed the conceited swimmer on the Aztec team. And I can't help but like those Olsen twins. At times, especially in the blooper reel at the end and in the interviews that appeared on the 'Challenge' program, they seemed more sophisticated than the cute little girls we have come to know. But they have yet to shake that adorable image.
It wasn't a great movie, and not a classic by any means, but it was Disney-style fun.
