I'm a big Herzog fan. Thought I'd search the web on "Ten Minutes Older" before I bought the DVD. Found the solitary review on this site and in particular the comments made about Herzog. They were so harsh I felt I should search for more reviews. Honestly, I've never seen anything Werner Herzog has done that wasn't unique, interesting etc.
Here's a snip from another site about Herzog's segment. This way, folks like me (who might otherwise run in horror) have a balanced view.
The third short, Werner Herzog's Ten Thousand Years Older [69], is a fascinating mini-documentary which examines the discovery of what might perhaps be the last lost tribe. Set in the Amazon, the film epitomizes Herzog's willingness to go to the ends of the earth to demonstrate his attitudes about civilization's debilitating effects on nature. Genuine tension arises in scenes such as the one showing the tribe's first contact with modern man, in which a native threatens to spy the hidden camera recording the event. When Herzog tells us that these few minutes of contact with the modern world led to the tribe's demise, the film suddenly shifts into a sadder, but no less interesting mode. Time jumps forward twenty years, and the effects of the modern world are made apparent. Even if it's not one Herzog's best works, it's undeniably an excellent piece of movie-making.
