I am (self-admittedly) ignorant of a lot of things in literature, and so was not familiar with the original work The Man In The High Castle was based on before I started watching the first season when it was released. Aside from the jarring prominence of swastikas and the like, I found myself intrigued by the premise. I think the most difficult part of the series so far for me was merely getting back into character dynamics after the hiatus between recent seasons.
