Query: Not as good as Michelangelo but worth getting

Readers of the recent book "Fortune Is A River" (also available here on Amazon) will have learned something of Leonardo's activities in Florence. This video is not of the quality of the A&E Biography of Michelangelo and was a bit disappointing at first because of that, but on subsequent viewings has grown on me. Leonardo is best known for the Mona Lisa and most know that he was also an inventor. He also was a child of the aristocracy and never completed most of his projects. The canal project described in the aforementioned book was a massive failure, but few have ever heard of it (I sure hadn't). If this video were made this year it would be bound to include something about that failed project and maybe give a fuller picture of his activities. Perhaps because his interests were so widespread his story is more difficult to tell in 45 minutes than is Michelangelo's.
