I do like that they really hammered home a couple of major points that many don't realize:
Washington's army got pretty fucking small as many Americans were not fully committed to this endeavor.
A lot of British would have been fine with the colonies leaving if it stopped the hemorrhaging of money and they still had trade, and a lot of American patriots/rebels would have been fine staying within the empire if things would go back to the way they used to be.
#2 is an amazing alt-history topic to run down the rabbit hole on - had the Brits backed off, listened to the American grievances, compromised in some manner (yes, they had enormous war debts still left over) and you don't have Washington, Adams, Franklin, Hamilton, Jefferson, Adams, and all of the other Founding Fathers getting together and building a new nation, what happens? If American remains a colony (or 13 colonies) into the 19th Century, what does that do with British military engagements and foreign policy into the 19th Century, Napolean, etc. What about the French Revolution? Just crazy to ponder.
