If you have missed any episodes, you can stream them at pbs.org. I watched each of the first five on my iPhone.
This documentary has been very well done. We were talking about it at an American Legion meeting the other night, and several of the members of my Post who served there had nothing but praise for it. I have found it interesting to compare to the prior Burns documentary on WWII. Even though one was considered the "good" war and the other a mistake, the valor displayed by our troops was the same (and so, too, was the cruelty--even in a "good" war, the experience of fighting it extracts a terrible price).
My uncle retired from the Air Force as a Lieutenant Colonel. He served as a Lieutenant in Vietnam, flying spotter planes as an artillery observer. He came home in his mid 20s with gray hair.
All in all, this documentary provides a good overview of our history in Vietnam. Even though I'm not really learning anything I hadn't known before (having taken a class on Vietnam during my undergrad days at Davidson), I would still recommend it to just about anyone. It is that good.
