As I thought, lots more people saw more of this than I did and there are some comprehensive thoughts from Richard . I'll add more links as I find them.
Update: Tractor girl also has some thoughts on this programme.
Agent K is annoyingly erudite, well-observed and cogent on the subject - why can't I have thoughts that well developed at the moment?!
Update: Chris has also now posted on this programme.
I'm now REALLY hoping to see it on video sometime.
