Query: Great Documentary and Wonderful Cover Art

This was a very good documentary to watch. Its very interesting and they show lots of animals and the strange things they do. They were very knowledgeable and filmed in caves, under water, volcanos, snow land under water and much more. I would recommend buy this! I purchased on amazon for $25. Bestbuy was selling it for $46.99 -_____-. The cover art comes with a slip cover!
