I get the impression that they aren't trying for a "graduate level" TV show.
So, those of us with specialist knowledge of AWI politics and warfare are not going to see everything that we know already, and would like to see.
One of my minor AWI gripes is the ubiquitous Betsy Ross flag. Way back when, I equipped 3 regiments with hand painted BR flags. Further "research" has convinced me that such flags were NOT used on the land battlefield. But, I never took the proud standards away from units that had them.
Anyway… The show pretty well shot down the Betsy Ross flag, naming no names. I can almost hear a loud "Harrumph!" from the narrator.
For those who ask…
The first time the whole idea of Betsy designing the flag came up many years after the war. It may even have been during the 1876 Centennial. Her grandson started the whole story. Not unlike many other stories, where an ancestor did marvelous things.
I was delighted to see Gostelowe standards, and the flag of the 1st Pennsylvania. Definitely not BR flags.
Plenty of things there, that "specialists" could pick out, like different color British facings.
I'm very happy with the show, and I've recorded it all.
