Ken Burns does a thorough job of presenting the causes and the facts surounding the civil war. Only thing I disagree with is that slavery was not the main cause of the civil war. There were other factors involved as well. Ken Burns set the standard that would be used in all of his future documentaries by using pictures and expert interviews. One contributor was historian Shelby Foote who gave expert information sourounding the civil war. This documentary does an excellent job in describing a very traumatic part of our American history. Ken Burns took the civil war from the cold pages of the history book and presented it as a human drama in which ordinary men were placed in circumstances that were beyond their control.
