It's a weird show that they bought from Sweden (well, the idea at least).
You get 16 people on a plane, dump 'em on an island somewhere warm, and let 'em play Robinson Crusoe. They get divided into 2 teams, and start building a camp (one for each team). Then they get to live on rice and bugs for some weeks. Every week there's competitions, one where they can win food an' stuff, and then the big, weekly I-get-to-go-live-in-a-resort-competition, where the teams compete, and te winners get to send one of the people in the opposing team off the island through voting. In the end there's four people left,and the final round starts. When they're down to two (by means of competition) all the others are brought back, and they then get to vote for one of the finalists, and the winner is...well...the winner.
That's a rough descripiton, but I hope you get the picture. Yes, there's people picking on each other, and, yes, they're hungry most of the time, but for some strange reason people want to watch this...
<phew> 'Nuff rambling done, anything else you want to know? Yeah, yeah, I DID apply to be in the first season here in Sweden, but they didn't want me... <sob>
