In Survivor and Finder's Fee, it is about what you would do if you could get away with it. Survivor is about your own integrity and where you draw your own ethical and moral lines. There are no rules.
Reality is a genre that seems to be here to stay. I don't know how many of the new shows will last, but the more competition you have, the harder that pie is to slice up.
I'm not one of these guys who says, Now I'm on a really hot show, better quit soon before I get labeled. That's the most ridiculous notion I'd ever heard.
