I finished the season recently and I thought it was a really good season. Outside of the ridiculous, out-of-nowhere end (sorry writers, making a crazy ending that made no sense isn't honoring Philip K. Dick, it's being creatively lazy), I was pretty satisfied with it.
Rufus Sewell was the MVP again. He's done amazing work with such a character. Episode 5 really put on display the ugliest aspects of Smith's personality and was another reminder why this guy doesn't deserve redemption. He is an evil man. But Sewell does amazing work that keeps your enthralled.
I would say that Chelah Horsdal was a co-MVP. She really stepped up prominently and held up her end of the storyline. At least she is able to see what John isn't and does the right thing in the end.
After Rufus Sewell, Joel de la Fuente has been the second best performer on this show. Like Smith, Kido has done terrible things and I don't think he deserves redemption either. But de la Fuente has always done great work with the character, giving him a dogged, single-minded determination to get things done that would be admirable if he wasn't the person that he is. His role in the post-Japanese Pacific States is fitting. San Francisco has become his home, one he clearly didn't want to leave and it makes sense that he would end up as a power-player in this new world.
The stuff with the BCR was interesting. I believe they were mentioned towards the end of last year but they should have done a better job setting up the groundwork. Still, their interactions with the Japanese were compelling. Given how badly things have been for them, it's understandable they would latch onto anything as an alternative. But if they think communism is going to work, they'll be in for a rude awakening.
Childan has a nice storyline and Brennan Brown has always done a great job with the character. He (and DJ Qualls in previous seasons) have always added much well-needed comic relief to the show.
It was fun to see some familiar faces pop up in guest roles this season. David Harewood from Supergirl as the leader of the BCR as well as Rachel Nichols as Helen's bodyguard.
Issues with the season...the lack of Cary-Hiroyuki Tagawa as Tagomi. To the show's credit, they really did a good job with his glaring absence from the show but it was glaring. He should have at least had an on-camera death scene where you actually see him. I guess it was a scheduling conflict with Lost in Space? But how didn't they shore him up as he was a lead? Tagomi was one of the most compelling characters on this show and was definitely missed.
Also missed was DJ Qualls. At the end of last season, it looked like him and Childan would start working with the Resistance but this year Ed is gone without a word. I guess he went back to the Neutral Zone.
Another complaint in Season 5 was the line that Patton was at the handover of West Point to the Nazis. Patton, really? He would have gone down fighting, not handing over West Point.
If there was something holding back The Man in the High Castle from being "elite" television, it was probably the actors playing Juliana, Frank and Joe. They were the weakest links of Season 1. By Season 2, they had stepped up because they were given better storylines. I liked Juliana kind of becoming the new Man in the High Castle with the book she created with the real history of the world in it. It makes it very much like book where the films were indeed a book. But her character still seemed to move around from place to place looking for a storyline and it's clear the focus continued to be with the most interesting character on the show, John Smith. Smith and Kido were the best characters on the show and were able to carry it in a way Juliana, Frank and Joe never were.
Really enjoyed the final season and the series itself.
