Thank you, Ken Burns and Lynn Novick, for this fine documentary. Like Burns’ other work, “The Vietnam War” is thorough, balanced, personal, “true.” Ten episodes, 10 hours in all. It required a commitment. It wasn’t easy, but it was important. No glib explanations here, no cheap interpretations; just the human experience in all its complexity and ambiguity. At some point, one realizes how different an experience this is from most of our consuming habits today.
