Query: Not Martin Sheen

First of all, the content of this documentary is excellent. However, it is NOT the version on Smithsonian Channel HD that is narrated by Martin Sheen. Make no mistake, it is the same documentary, just with a different narrator. Unlike Sheen, this narrator is outright boring. Every other aspect of this 6-part documentary is the same. I was very disappointed in this product, as I loved the one I saw on TV.
