Alan Moore disagrees with you. I haven't read it, but his complaints certainly sound well-founded.

SPOILERS...?

He was complaining that in his original work, he was trying to portray fascism vs. anarchism, but he wasn't really trying to present one as inherently morally superior. He felt it was crucial to present some of the fascists as doing the wrong thing out of well-intended motivations, and, conversely, not presenting the anarchists as the cut-and-dried heroes that the movie did.

Hollywood doesn't really do moral ambiguity well. Confuses the test audiences. Villains must be bad, etc, and so we get a dumbed-down movie that loses the key theme of the book.

You can argue that it's a good movie, but I don't think it qualifies as a good adaptation.

Spider-Man 2 and Sin City, I think, fairly nailed the spirit of their source material.
