“The Man in the High Castle” should be the program on everyone’s lips after November’s election. After all, the show takes place in an alternate universe in which the U.S. has lost World War II, leaving the Nazis and Japanese empires to divvy up the states. Streamed through Amazon, the show isn’t beholden to any strict network guidelines around language and content. Instead of saying the pledge of allegiance in the morning, school children turn to a picture of the Fuhrer and perform a Nazi salute. The show’s premise is eerily close to discussions and debates rolling around the American zeitgeist now. And yet, it’s about as soft as the “Edelweiss” cover that opens its episodes.
