I just saw that Adam Curtis won a BAFTA for his three-part documentary series, The Power of Nightmares.
I had seen the documentaries on BBC and remembered how great they were. I did a quick Google search for them and found that they're availiable to download, in good quality, here.
As far as I can tell, the download is legal too.
They're really, really great documentaries, which challenge and educate your opinions on both American neo-conservatism and extreme Islam. I can't recommend them enough. Did anyone else see them when they were shown?
The three files are fairly big, but shouldn't take too long if you've got a good enough broadband.
