The film largely filters the book through a US lens. It doesn't do so heavily, but that does twist it away from the book's anarchist tendencies. (I also never felt the lurch in the film made any sense. The scandal wasn't big enough and the voting patterns were nonsensical. But then I guess those details don't really matter too much!)
As for the comic, I agree with Colin. It's been a while since I read it, but the story for me was more solid and more interesting than almost everything else I've read by Moore. It has heart. It's also brutal. Like Colin says, even the antagonists aren't cyphers and feel human, albeit ones that are on the wrong side of history. I also echo that I'd much prefer a B+W version of the book, but I suspect that's either impossible (in the sense no B+W art survives) or DC just isn't interested (perhaps due to the mess that was created when it took on the series, which has subsequently denied Moore the rights to his work back).
