I liked the movie. I thought they handled things in a surprisingly even-handed way. Yes, with a little effort, you can perceive a slight slap at Trump, but it’s barely there. If they wanted to say “Trump is a Nazi” they really should have tried a lot harder. So, I consider it pleasantly neutral.
I think the big lesson is that people are always flawed. We are made that way. We do bad things. We follow bad leaders. Afterwards, we may say “Never Again”, but it always happens again. We just keep making the same mistakes.
Goering scores key points by pointing out simple truths that much of what the Nazis were accused of doing, was exactly the same as what the Allies were doing. Moral superiority is in the eyes of the beholder. The big difference — of course — was the death camps. Six million Jews, and millions of non-Jews killed by the government. The Allies did not do that, only the Nazis. That, in the end, was the real crime of the Nazis. But without the Holocaust, the Nazi Regime starts to look like a whole lot of other authoritarian governments. I don’t know how many viewers will interpret the movie that way, but that’s how I saw it: Big Government does Bad Things. All the time. Everywhere.
Also when the world mostly ignored The Armenian Genocide, that convinced Hitler that eliminating the Jews wasn’t all that big of a deal.
