Based on a book file Philip K Dick, it is an exploration of an alternate dystopia where Germany and Japan won World War 2 and are in a cold war like situation. The characters are well formed. The cinematography and music are exceptional. I see higher than usual rate of lingering shots, with excessive glancing. I am not a big fan of this cinematographic style especially when implemented in excess (and lacking in taste, as in the Twilight** series.) Given that it is creating a futuristic world set in the past, a rather strange concept indeed, I am inclined to accept and appreciate it. Some ideas are typical of Philip K Dick, most seen in his various works.
*Multiverse - I should look this up. I am, rather, I was, under the impression that this is a word used in the comics world alone. I did not expect its use in the TV show to describe multiple alternative parallel universes, although that is exactly what it refers to. What is the history of this word? Perhaps next time.
** I have neither seen nor plan to see the Twilight series.
