Here's a wiki link to explain it best.

Watched the first two and have the last one recorded. I'm not fussed the way he seizes on individuals (like Ayn Rand in the first episode) to thread through the story - it doesn't make any sense to me. His angle on the failure of the communications led revolutions in the second episode was very thought provoking.
One thing you have to give him credit for (and the BBC for that matter) is having a go at a metanarrative to explain the world around us today. It used to be the norm in social science, now it's seen as 'audacious'.
Viva Adam Curtis.
ps. talking about being watched over by machines of grace - what happened to the 9/11 feature film thread I posted last night?
