Originally I thought Ken Burns' Civil War was just OK. The more I watch it and consider it, I believe it's nothing more than a bunch of revisionist history played out in a pleasing format.
According to Burns and his "historians," the Civil War was all about slavery, and offers apology after apology.
I won't subsidize it further by purchasing the DVDs.
YMMV.
I've seen Burns on a few talking head shows and he's a big Bush supporter. He is race obsessed, however (see his "Baseball" or "Jazz)
