Good concept although it's very formulaic. Very predictable and quite clearly staged in places (as most US "reality" shows are). Still though, it's entertaining as I do think that the celebs feel anxious carrying out the "survival" tasks. Really wish they wouldn't keep banging on about faith though. Utterly stupid to think that some all powerful God is looking after these guys acting/sporting career while he lets babies starve to death in other countries. Keep your boring faith to yourself. If they run a second series I hope they crank up the realism a touch and lose the formula.
