Riotus, speaking of spy TV shows, have you seen Little Drummer Girl? It's directed by Park Chan-wook (Oldboy, Handmaiden etc) based on Le Carrè's novel, and it's just 6 episodes.
I'm only 1 episode in, but looks very solid so far, great cinematography as expected.
There's a good cast too (Michael Shannon, Florence Pugh, Stellan Skarsgard).
