I stumbled upon this series by accident and was surprised that the ratings were rather low. I assume, looking through the statistics, that younger people are interested in more commercial and simple-minded content. The series impresses by meeting exciting people who have diverse but always exciting stories to tell. In addition, the series offers a lot of great footage and comes in a well done mix of all the aforementioned elements. It never gets boring while watching. I was much more surprised at how many different aspects you can get out of one subject, like Death Valley (episode 1). Too bad there aren't more series like this. From me therefore clear 9 stars...
