FWIW the best survival show I've seen is Survivorman. He has no camera crew, just him and his cameras.

I gave up on "Last One Standing" after four episodes. That was crap, although I suspect much of the blame should go to the editors and producers for playing up fake interpersonal conflicts. But the regular show is pretty much what it always was. It has always been more about mental and emotional strength than physical survival. The survivors' real personalities come out under stress and sometimes they are not pretty. But the nice, generous ones shine through.
