I can't refute your criticisms about not developing an "alternate America", but I still like the show. No where near the appeal of High Castle. A shame that one had to end. Another quite worthy SF show, IMHO, is The Expanse.
Even though I ripped it apart, I won't deny that the show is watchable, especially if you favor mainstream network TV shows. Say what you will about the writing and the story, the actors were all pretty good and the show looks great. I definitely didn't like it, but I didn't absolutely hate it either. In the end, I just found it to be a huge disappointment and that upsets me more than if it had been flat out terrible. The concept is great. Seeing a great concept wasted is really infuriating!
I loved High Castle. It wasn't perfect, but it was a very satisfying show on many levels. I absolutely loved the world they created and I really appreciated that we got to see so much of it. As I said, this is what really bugged me about FAM. The show's creators want us to believe that a different space race is happening, yet feed us only crumbs about this new America.
I feel like FAM could have taken each of its major storylines from the first season and pretty much made a season out of each one. Women in the space program. Instead of a patronizing whirlwind, it should have been a whole season. The relationship between the gay astronaut and gay mission controller (sorry, I found the characters so boring I only remember a few names) was so poorly constructed. Again, that should have developed over time. There should have been more to it, not just a marriage of convenience amid a rapid fire succession of social justice issues. Father/son relationships and losing a child? I mean, come on, that deserved a lot more. It was all superficial. I loved BSG, but I'm pretty convinced now that BSG was a fluke for Moore.
I love the Expanse! The first season got a bit SyFy cheesy at times, but it's one of the most realistic looks at where humanity might be in 200 years. No Star Trek fantasy. I'm so glad that Amazon rescued it. Season 4 was excellent. The finale left me totally gripped. I might re-subscribe to Apple TV+ when Foundation launches as I imagine my free year will expire before then. There's really nothing else on ATV+ that appeals to me as a viewer at the moment, but I'm certainly open to trying new shows if they ever launch one that looks interesting.
I still find that Netflix offers the most bang for the buck. It's the only streaming service that I find worthy of having year-round, versus the subscribe and binge strategy (like I did with CBS All Access for that rancid piece of excrement called Picard). I just started season 4 of 3% on Netflix. If you haven't seen it, I highly recommend it. It's a pretty low budget Brazilian near-future sci-fi show with some very satisfying twists and turns. The creator has a new show on Netflix about drones that looks intriguing. I'm going to check that out next.
