The orginial show was pretty good, and all of the information Myke Hawke was useful, especially to those who aren't "in the know" about jungle survival. The idea was based on a guided jungle tour, gone wrong, and the two of the four survivors tald their story, and how they made it out. Myke Hawke simple explained how to do simple things that could have made a difference in their ordeal. Preparation, gathering, water, etc.
I think they kept repeating his background as a way of saying, this guy has been there done that type thing, same as they did with Les Stroud in the Stranded in the snow one.
Anyways, if they repeated the full show on Discovery, it is worth watching for sure.
Edit: it was the SCIENCE OF SURVIVAL, and they based it on the "I shouldn't be alive" series.
