Now go watch the darn thing.
(spoiler: it's a parody of Curtis's methods)
It's not considered his best stuff, All Watched Over By Machines of Loving Grace is probably most relevant to HN and all three episodes are well worth watching.
IMO his best stuff is on the coincidence and movement of political power. Check out The Trap and The Mayfair Set. The Power of Nightmares is good too.
The Clinton affair angle was also out of proportion.
You can find them on archive.org too. He tacitly encourages people to share and distribute them.
See the following brilliantly observed parody for the reasons to take him with a pinch of salt: https://www.youtube.com/watch?v=x1bX3F7uTrg
That said, he is one of my intellectual idols, however much he does enjoy gimmickry.
E.g. why are you on HN? Is it because you're bored while something is compiling? But you know that you'll spend more time on HN (or slashdot or whatever) than it takes for the compile to finish.
And why is twitter so popular? Isn't 140 characters the antithesis of patience?
I can certainly take the time to read long articles, but I didn't know this author. So that makes him one of literally "thousands" of articles, tweets, etc competing for my time every day. That's why I generally flit thru articles.
His documentaries are among the best I've seen (and he has quite a few). Most are available on Youtube (or in a torrent collection, if that's your thing).
I recently watched "It Felt Like a Kiss"[1], and it's quite the piece of art. No narration, all great music.
