I love it, definitely one of my favourite recent series. Was skeptical at first when it came out, but decided to give it a go and I'm glad I did; binged Season 1 in two nights It's a sort of alt-history which starts with the Soviets beating the Americans to the Moon, and from there on, the space race truly picks up speed. They really captured the spirit of the 60s/70s, in that aspect it's like Mad Men but with NASA instead of the advertising company, and with more "action" to keep it balanced. Especially interesting if you're into the history of the space program; as although it depicts both historical and completely fictional events through the prism of alt-history, it still has a lot of real historical characters (Wernher von Braun, Neil Armstrong, Buzz Aldrin, John Glenn, Gene Kranz, Deke Slayton, etc.) and old footage (used in a very clever way too, I must say). Cinematography, characters and storylines are all top-notch.
