Okay, just a thought... I think we can all agree that the most dull season of Survivor was Survivor: Thailand. One of the main reasons for this was, in my opinion, because the older generation of one tribe stayed allied to a tee, and there was very little challenging of the ranks, making it easy for Brian to win.
Unfortunately, I do see the same possibility happening here. Sure, the young people generally make good eye-candy, and as I am 25 myself I can relate to them more, but with the exception of Richard Hatch and Rupert, the most entertainingly aggressive players have been younger (ie. Rob C, Rob M, Jon, Kelly, Saundra...). I think this is because the older generation just has more patience usually. They won't look five episodes down the road, not see their win (like Rob C. did), and suddenly switch sides. They're more likely to stick with what they have, and avoid plotting too much until the end is right in their face. This happened with the Taki alliance and Brian's alliance (forget the name). Let's be honest, Richard got pretty lucky (it seems we often forget that the deciding vote was Greg's, who simply asked Rich and Kelly to pick a number between one and ten), and that made Richard's win a hoot, plus the fact that it was new. But Survivor: Thailand...arg..Brian had it too easy. He got a solid alliance together and was the only one that made one on one alliances with everybody except the useless Jan, and everybody just went along with it to the point that Brian could just decide exactly how he wanted the game to end. I doubt Brian would have had simliar luck with a younger alliance. Correct me if I'm wrong.
It seems the same trend is happening here so far. Hopefully, the tribal mix up wioll shake things up, but i get an awful feeling that the majority old will still stick with the old. Personally, as much as I like Amy and Chad, I'm really rooting for Brady, John K, Julie, and even Eliza, just to keep the show interesting.
