i've only seen the first two episodes, but here's my two cents
:

too early to really say, but I think it's pretty good. i'd turn the dial down on the backwoods cussin though. yeah, we males tend to let loose a bit when left to our own devices, but what does this have to do with survival?

1. the advertising.
not exactly show-specific comment, but the ads and spots are playing up the personality conflicts WAY too much. That's sort of the point of the show, but it should be about the contrast in methodology, not bickering.
actually, that's a pet peeve i have with Discovery's advertising in general lately. Way too much "drama." It's a turn off for fans of the genre who, like me, don't care for the "reality show" type stuff, and those who do like it get set up for disappointment, because there's not that much actual conflict going on.
2. Maybe ease back on the epic-journey music, as it's just doesn't fit what's on screen. He's chasing a porcupine, not battling the Cloverfield monster.
3. SHOW US WHAT'S GOING ON! if the point of the show is contrast in methodology then we need to see more of their respective methods. ok, Cody doesn't wear shoes and Dave thinks he's a crazy hippie. we get it; move on.
