Your post made me think... I'll bet there are people out there who want to do this show...even IF big $ wasn't involved.I totally agree with you.. in some ways this show has turned into Survivor. "If you promise to never write my name down I'll take you to the final four with me Dude, promise!" Then stab 'em in the back because that is THE WAY THE GAME IS PLAYED! People think Survivor is different because it's all about money and The Biggest Loser is about people changing their lives, but we can't forget that there is money involved and money changes people. I think we all feel an underlying empathy and caring for most of the people on this ranch each season, and I will often choke up during an episode of TBL. I can't ever remember tearing up in front of Jeff Probst.
In some ways I think this show could benefit from one feature of Survivor: The jury deciding who wins, or at least has a say in it. Imagine Jeremy and Conda facing a panel made up of Cassandra, Emily, Mike, Chism... and having to explain how/why they are still there and the jury members aren't. I'm sure some of them feel played and regret helping the Diabolical Duo now. At least on Survivor there is a way to get back at 'em!
