Why on Earth would you want to listen to a reality talk show (if you can even call it that) queen talk about things far removed from her forte? Over the decades, my family and I have watched all of Sir David Attenborough's nature video series (I still have some in VHS version, lol) and what makes his version vastly superior to Oprah Winfrey's attempt is--to put it bluntly and and simply--the man's world of knowledge and the infectious enthusiasm he has for the subject. As for why Winfrey was chosen...? Your guess is as good as mine. But like they say...a sucker's born every minute.
