First of all, it was interesting to see some parallels with our reality: Japanese States experiencing basically the equivalent of the civil rights movement, American Reich basically the Chinese cultural revolution (ie, destroy the old / young people buying into it). The show seemed to paint the Japanese states in a way where positive change there seems more plausible. The Japanese admiral wanting them to be less murdery, Kito showing compassion to the prostitute girl, Tagomi of course.
But the whole idea of "lol revolution! we beat teh facists if we show movies" seems REALLY far fetched in the American Reich with any sort of hardcore Nazi leadership in place. Maybe, and a big maybe, if somehow John Smith ruled all of the Reich you could maybe see some change. But that seems unlikely without really shit writing and the youth are all fullblown kool-aid drinking Nazi loyalists. Even if you could get buy in from the adults who remember before the war, the kids/college aged people have full buy-in because they don't know any better. Change would have to start with the youth, and I just don't see that happening because of a bunch of Allied Victory films. Frank surviving the terrorist attack was also pretty wtf, but at least they got rid of him (again). He isn't healing from that lol.
I did like how Juliana called out how WTF the Nazi machine plan was, though, because I was thinking the same thing. How can you conquer a world unless you can scale the thing up to the point where you can basically just drive a fuckton of tanks/jets/etc through the portal? Although if the revelation in the final episode is accurate (that you can only travel to a world where you are dead/don't exist), then that seems to be kind of odd. That means Tagomi is dead in our world? I mean, I guess they could say he died in a ditch drunk or w/e and his family just didn't know it, which is why the show Tagomi could go there.
Anyways, as usual, John Smith was the best part of the season. Curious to see where the 4th and final season goes. Juliana maybe is traveling to the world she was executed in? Or maybe the world Trudi came from this season (since Juliana was dead there)?
