Well Bear sang a good rendition of 'the bare necessities' on british tv one time so can't be all bad.
But as you say it's all staged. Whenever he 'parachutes' into trees or slides down a glacier, there is always a camera crew at the exact spot he comes to land.
That doesn't affect whether the advice is good though.

And you notice survivormans 'knife' is a multitool? And seems to work for everything.
