I saw this 4-part documentary last week and it was wonderful.
My brother and I watched them over two nights, and we constantly were looking at each other and grinning at the way Bill Whittle framed things...we both laughed aloud when he talked about Sputnik and the dog Laika...
“Those vodka-swilling, aetheist, Communists were sending a dead dog over our heads once every 56 minutes!”
(I had to paraphrase there, but you probably remember that part of the episode!)
