for the next season I hope they try to get all of the kids to perform in all the challenges, no matter what. I recall a tv show about gamers a few years back where all the kids would compete against one another playing a video game(say guitar hero for example), and they would take the two lowest scorer's and they would be forced to challenge each other again at the end of the show, loser go home.
I thought it was kinda crappy that some of these Nerds had to put their butts on the line over/over again, like Danielle(sp) I swear she had her ass on the line at least 4 times, meanwhile the girl that won the whole show, was only in two challenges where it was just up to her(and not team). I didn't even like Danielle but I thought it was crappy that she had to constantly be forced into the win/or go home scenario's.
Also, some of these challenges have to be more cerebral, the final four had three females, and a guy racing on those battery powered scooters, and the male in this situation was at a severe disadvantage because he outweighed all the girls by at least 60lbs, so of course his scooter would be the slowest.
