Season 3 things that seemed hard to buy
1. Juliana and a close friend of hers both know the authorities are trying to find them, but they never think to adopt any sorts of disguises, or even dark glasses.
2. How can Himmler spend so much time outside of Berlin? Doesn't he have an empire to run?
3. Mengele was a physician. Would he really be the one leading a project to build a machine (mechanical engineering problem) or travel through time and space (possible physics problem)?
4. Why does the Smith family worry so much about medical tests? They have the power to bribe, blackmail or strong arm the doctor to get the results they way. Even presidents in western democracies are able to do that.
5. Why is the Tamlyn Tomita character in the show? Her storyline does not seem to add anything important to what is happening.
6. Would the Nazis, who had decried jazz music for a long time, once the finally won the war, actually play it at one of their major parties?
7. What would be the point of the big Nazi plan with the machine. Even if it were to succeed, to what end? They haven't even fullly achieved the goal on this world.
