Oldie but goodie

Rico says he's been watching Tinker, Tailor, Soldier, Spy; the original series with Alec Guinness, not the recent movie with Gary Oldman. While Oldman is a good actor, he's no Guinness, sorry, and the six-episode series enabled them to play out much more of the back- and side-stories...
All in all, much better; worth getting it from Netflix or buying it, as Rico did. (Soon to be followed by Smiley's People.)
