I've been watching The Thick of It, which was first broadcast on BBC 4 in 2005. It's marvellous stuff - close-to-the-bone, Machiavellian, grotesque - and has me thinking that Armando Iannucci makes a better comedy writer in, say, 1985, than 2005. That's not to dismiss the very noughties Nathan Barley, whose compelling discomfiture - despite a weak and bitty structure - was upstaged by critics' and commentators' hilarious offscreen attempts to find a fingerhold in its scree of irony.
Agreeing with the comments elicited by YouTube clips is generally a bad idea, but those attesting to the perfection of this series are pretty close to the mark, I think. Viewing feels very timely and pertinent in current circumstances, too.
