I'm painfully aware that I'm a new boy to this forum, but I'm a little bit passionate about indigenous cultures, so please allow me to dip my toe in the water.
Jimmy Nelson needs no intro. Clearly an awesomely experienced guy. But I did get a clear feeling after watching the 20 minute intro, that it really was all about...well...Jimmy Nelson. It certainly had a 'celebrity fly-on-the-wall' theme going on throughout the whole film. To top it all off, I think the narrator was the same guy who sells Dodge-Ram Pick-Ups on AFN.
I somehow didn't get the feeling that it was aimed at the discerning, think-outside-of-the-box bushcraft enthusiast. In that respect I think that the many indigenous tribes in question may have far more to offer us than dressing-up for photo-shoots.
Still, the pics do look great.
