Margot Robbie did exceptionally in this, I thought.

John Washington was as wooden as the log in Twin Peaks... and even less interesting.

Tonally and from a sense of narrative flow, I found this to be sort of odd and not entirely successful. How much of these problems, though, are really a result of the other issues is hard for me to say. Can you ever be certain if tone or flow not quite working is just because some acting isn't convincing or because a humorous moment is falling flat?

The subject matter they've, let's be generous, 'ostensibly' drawn from is interesting, but they've done some weird stuff in this most-obviously changing the names around, I guess because they've certainly confabulated so much of the details about what exactly happened with the conspiracy of a couple people in the American Legion at the time who tried to cook up a bizarre plot.

The most egregious fabrications, though, were not the events, personal details, or the names that have indeed been substantially changed from reality to the point this either must be considered mostly fantasy or two completely separate scripts slapped together into a single project, but rather the claim of Nazi-Germany-sponsored eugenics clinics. These were, in fact, usually state-run clinics in the USA, and usually with the backing of various Ivy League institutions and institutes on 'human hygiene', particularly popular in places like California.

Just as the China 'one-child' population control policy was formulated and exported from the west to that country, Nazi eugenics was exported from the west to there, not the other way around. US and British banks had funded not only the ousting of the Czar and the rise of the Bolsheviks, but the rise of Hitler, too. Later on there were certainly groups here who were followers of Hitler, and a back and forth occurred, but to treat the early-30s eugenics movement as being some hidden, underground German export to the USA was a distortion of history in order to deflect culpability of our own country and especially west coast academia in the events of that era.
