Just started (first two episodes) The Plot Against America. Not bad so far.
After the horrors of The Man in the High Castle I couldn't watch another WWII era alternate reality story. I'm also planning on reading the book. Interesting tidbit, the spy author Len Deighton published in 1979 SS-GB which was a police procedural in Nazi occupied England. It was a good book which was made into a BBC series in 2017. I've not seen and it's supposed to have an open ending leading to a second season which isn't going to happen.
