A dystopian british nation must be saved by the tyrannical totalitarian government under which it has become subjected to since a recent nuclear war that has left much of the Earth crippled. And who will act as the people's modern/futuristic Robin Hood, to inspire hope within the masses of a spiritually tattered land of The United kingdom? In this case, it will be the mask vigilante known as "V". And so confident is this anarchist avenger of the masses, that he requires naught but swords to combat gunplay, a name no longer than that of a single letter, and a mask based not on of fear, but one based instead on a visage of a happy but rebellious historical figure.
Alan Moore's storytelling is just so rich in detail, atmosphere & concepts, that it can almost seem impossible to capture even just a sliver of it's essence onto a film adaptation. Therefor, even though this movie quite obviously cannot compare to the comicbook series, just the fact that it was able to retain anything at all from Mr. Moore's work to any kind of degree of consistency to the story
(which, IMO, is the only movie to do so far) is enough to mark it as a success for me.
