Where's Eva Braun? Hiitler should also have dogs.
Sometimes I have a hard time with the Hitler character in this because there's nothing except the brief scene of him painting that references personal details of his life. The actor does a great job and looks the part.
But for example, when they were going to see Hitler in his castle in Season 1 and the castle is increasingly creepy and high security as the point of view approaches his chambers, I wanted some contrast of weird and normal. His tastes were actually very conventional.
He should have been revealed to live in a cozy apartment with an elderly (but much healthier than him) Eva who fusses over him and Blondi IV. Then go into the room with the films after this interlude of normalcy.
