i think some of the video is fill in, but not all. reason for saying that is seeing m16's relatively early in the war.
as to the rest of it, as it was an area of interest, indochina, and a good library, a lot of it was surmised even at the time as to the administration leaders. If the military would have been turned loose, it would have been over pretty quick. We have an excellent military great at breaking things, which is what they are suppose to do. We are lousy at nation building.
I remember that incremental escalation b.s. real well. Johnson wouldn't take a dump or get off the pot.
The series is just to me confirming what i believed or thought at the time.
The government has lied to us a lot, and still continues to do so.
I stopped being a virgin in that respect circa 1966.
But it sure should help younger people understand it when us old fahrts talk about a special place in hell for johnson and his cronies.
