Seconded as well. I've yet to see the final episode, but so far it has been very good. As a non-US'an the Vietnam War was dealt with by a few paragraphs in the high school history books. Oh, and of course by watching movies like apocalypse now, full metal jacket, and, yes, Rambo 2. So it has certainly been very interesting to learn about the background, politics and the higher level military situation.
