Query: Greatly covers Tolkiens acheivement

I believe to create an autobiography about a man such as Tolkien video creates a great picture and understanding of the concepts that that particular person or persons is trying to get across to its audience. This documentary revealed the aspects of Tolkien's life that were key to writing the amazing novels that were produced. I recommend this to anyone that is a fan or just curious. AMAZING!
