Why is it that Peter Coyote is on every single PBS documentary? Do they have him locked up in the PBS basement or something? I swear, his voice over is getting so old and stale, and on this DVD, it just puts me to sleep. It just sounds like "Yosemite was... blah,blah,blah ... President Roosevelt... blah,blah,blah..." And, the picture isn't that great... not like the 70mm filming that something like the movie Baraka had. It seems like any half-talented junior college student could have pieced together this DVD with grainy, archival footage and lousy voice over. How come we see so little of the desert too? Its all about the main stream parks like Yosemite and Yellowstone, like we haven't seen a hundred films about that by now. What a joke! What a total piece of garbage! Ken Burns, failed once again. TOTAL FAILURE. WASTE OF MONEY. HORRIBLE.
