No matter how familiar the "Survivor" concept gets, it still seems to work.
Starting fire, this time out, was no big deal - but building a shelter that could keep out the elements, and the beach crabs, turned out to be a lot trickier. And this time there was nudity, lots of it, during the very first immunity challenge.
Another reason "Survivor" continues to work so well, edition after edition, is that Mark Burnett and company continue to cast the shows with such an unerring eye for eccentricity and potential volatility.
