I just finished Silo season 3. I really loved it too. At first it felt like a Fallout knockoff and a bit predictable, but then it quickly establishes itself as its own thing and goes in some pretty surprising directions. I thought season 2 especially was fantastic.
Also on Apple is For All Mankind, an alternative history show about the space race, which I also absolutely loved. Again, one of those thumbnails I saw for years before clicking on it. It’s produced by the guy who did Battlestar Galactica and one thing I loved was how quickly it would move the plot forward at times. In the age of glacial pacing in most TV shows, this would sometimes cover years in a single episode. At first it feels too quick, like it’s skipping over things, but eventually you start to really love the ride. I still have the fifth season to watch, so am saving that one.
Slow Horses is also one of the best shows on TV.
