I like Survivorman a lot.
I suggested in another post that some of the mistakes Les Stroud makes are intentional to show the audience "what not to do". Even so, the show is about improvising in a survival situation that he and the producers of the show set up. Regarding that, he's still alive and to hear him tell it he's not yet used the satellite phone he carries other than to make sure it's working (he's mentioned that it doesn't connect about half of the time), so "wrong" is somewhat relative.
Of course that's just my opinion. Your mileage may vary.
In the particular show you mention (if I remember it correctly), had he done everything "right" he would have busted out the space blanket that he had and used it on the very first night versus waiting until he made it down to the treeline and had built a shelter.
Heck, if he had done everything right he would have been better equipped for any survival situation in general. <img src="/images/graemlins/laugh.gif" alt="" /> I mean he wasn't even carrying anything to start a fire and he ended up breaking a video camera to get a lens with which he started a fire on the 3rd or 4th day.
But the show isn't really about having the right equipment to survive it's about improvising with what one has on hand, especially one's own mind, to give a person better odds in a survival situation.
Truthfully, by the 3rd or 4th day of most of the shows I expect to see Les make far more mistakes than he does simply from putting himself into starvation by burning more calories than he takes up. I'm generally surprised that we haven't seen him rant like a nut yet and start talking to "Harvey". <img src="/images/graemlins/laugh.gif" alt="" />
Anyway, here's a link to that previous discussion about Survivorman:
