You guys are missing out on his whole message of anarchy in the comic. He doesn't want anarchy that results in chaos in death. That is the Land of Take-What-You-Want, which he does not want. But it is a step to his goal. His goal is the Land of Do-As-You-Please in which a society has anarchy because they want it. It's about people working together to support and help each other and make everyone happy.
And I think the movie was a terrible film and I wish I never paid money for it. It was a piece of trash if you ask me and the changes were far from cosmetic. Take just your example of Evey. I don't think many people care
that much about the prostitute thing. It's more about the fact she previously had no thoughts of rebellion or reason to be against the government, but V manipulated a young, impressionable girl to do his bidding. There's one point already that makes the comic much deeper than the movie. Then consider what this says about Codename V's character- is he a villain or a hero? Again, another aspect that makes the comic much more thought provoking. I could go on and on....
And to respond to a question closer related to the original question:

What I'm saying is "Moore if you're not interested in making movies, that's fine; go write some more of your wonderful comics. But if you don't care about these films and you didn't want to help out with them, then why are you complaining about them?"
He doesn't want to help them because he doesn't want them made in the first place. I may be wrong, but I don't think he ever said he doesn't care. He just doesn't want a piece of crap out there parading under his name. He makes comics that don't work as films. He feels there's too much thought put into each and every panel, by himself and whoever the artist may be, to function as a film. He said something to the effect of "in a comic, you can go back and re-read panels and check back if something recurs; you can read at your own pace. You cannot do this with a film". If he doesn't want a film to be made and people insist on producing a film he finds to be garbage, he has every right to complain. He shouldn't be forced to help just to make a mediocre film; just because he helps doesn't mean he would be allowed to do whatever he wants and he would likely be unhappy with that. And, once again, the bottom line is- he doesn't want a film to be made.
