I just finished Thailand today. I am actually noticing how challenges played into the social politics so much more back then. Of course they had the challenges where you literally showed your pecking order by knocking others out of a reward, or even immunity. (This would actually be fun to see brought back.) But the person who wins rewards had a much bigger burden when choosing someone to go with them. Now people mostly pass it off as gameplay, but back then it could ruin your whole game. It would be hard to follow some episodes without the challenges.The only one I've gone back and re-watched so far is the first season.
It's interesting to see how different it is from (some) of the players perspective, and the show's perspective.
Jeff is describing it as more of a social and survival experiment, where people could be voted off because they don't contribute.
The players, several episodes post merge are quaintly realizing that only Pagong members are being voted off.
They should release a version of the show that edits out challenge footage, and just states who won. It would be easier to find the time to re-watch as the episodes could be cut down to the twenty minute range I imagine.
On another note, Survivor South Africa: Island of Secrets is six or seven episodes into their latest season and is worth watching.
