A major theme of the series is how the American public was lied to about the reasons for the conflict and what happened during the war, with an emphasis on how successive Presidental administrations knew that the war was essentially unwinnable.
It also clearly highlights multiple times how the Americans were seen as invaders by much of the Vietnamese population.
There are legitimate reasons to criticize it but I wouldn't describe it as a whitewashing (I'm only 80% through it so maybe the tone changes later in the series).
I agree. The Americans look bad. The French look bad. Even worse is that at first the Americans looked like an ally since they were once a colony. They way they left the Vietnamese out to dry after WW2 is a tragedy.
