Just watched Episode 9. Two more participants out, I thought one of them at least would last longer. We also got to see Sam's first attempt at bowhunting. Not much luck in that department though. There just doesn't seem to be any game in that environment. So the bows and arrows are pretty much dead weight.
With the last episodes focusing more and more on personal drama over content the show has lost some of the initial appeal IMO. Nevertheless, now that the last two men standing have gone beyond 40 days out in the woods you can see the effects of malnourishment and general physical deprivation very clearly. Heck, the show should be titled "Weight Loss Camp".
