IMO - - its another of the typical useless 'survival' shows. I watched an episode and they spend a lot of time/energy on stupid projects rather than the basics which might keep them alive in a real scenario. They try to be 'inventive' with Rube Goldberg b.s. contraptions, when the same results could be achieved with much less input of vital resources. 'Survivorman' with Les Stroud is probably the best of the genre. But most of these shows seem to need to create 'drama' in order to hold the limited attention spans of their audiences, at least long enough to air the next commercial or flash a product they are endorsing.
(Yeah - - - I've taken real survival training - including that from US Air Force survival instructors and LE SAR supervisors & trainers. Don't waste time on these t.v. programs.)
