The problem with the show is the writers unintentionally made people like Obergruppenfuhrer Smith more likeable and sympathetic than Julia and her boyfriend, and they got mad that people vocalized this. People weren’t supposed to like Smith as a complex character but just unabashedly be for the ever so cliché resistance.
Season 3 rectified this by killing off a lot of people and essentially nuking the script.
I'll probably catch three more episodes tonight on Prime through Roku. Finding out that Julia was the daughter-in-law of the Pacifist Japanese Trade Minister, in an alternate reality with their shared memories was a master stroke of writing in my opinion.
