This is a great documentary and is a must see. The previous reviewer is an obvious white supremacists/racist who is quick to discredit John Henrik Clarke's telling of history but has no scholarship to challenge him with. Dr. Clarke is not re-telling history but correcting what has been omitted about Africans specifically and our place in the history of man. It is exactly this type of nonsense that makes the documentary important. Dr. Clarke became a historian because of the lies and omissions that had been told by white historians who attempted to write Africans out of history to support the ideas of African inferiority to make it seem as if only white people had done anything worth while on this planet. The only contempt Dr. Clarke has is for the white supremacist who pose as historians. In short the documentary is a good guideline to anyone genuinely interested in African history beyond the lies and who is willing to do their own research also. Very proud of Mr. Snipes for narrating this story of one of our heroes who spent his life in the service of his people. Thank you Dr. Clarke for your "great and mighty walk".
