The game of Survivor, the formula and dynamic = perfect
It's really quite a brilliant concept.
Two different teams that compete against each other.
They need to work together, within their tribes....but also need to start strategizing AGAINST each other, step by step....and slowly turn on each other, within their own tribes. It's like a chess game, where you have to be cognizant of your moment-to-moment moves....but also think 4-5 moves ahead. You have to keep your tribe strong and competitive, yet you also have to start eliminating the best players....within your own team!
That's why this show has endured for so long. It never gets old. The formula is perfect. Take this social experiment dynamic....put it in an exotic location....make sure there is eye candy. Perfect show.
But Jeff is the glue that holds it all together. As great as the formula is....it can't work without Jeff P. Can you picture this show hosted by, say....Mario Lopez?
