This is a quite remarkable book, because not only is it supremely satisfying, but it manages to break a whole load of apparent rules for the genre in the process. The ‘big event’ (the destruction of the Houses of Parliament) is over in the first few pages, and the ending is anything but conclusive. And yet it works, extremely effectively, as a story.
And yet underneath that there is an examination the nature of the society. Moore shows us not a conflict between anarchist chaos and totalitarian order, but rather a choice between order and chaos, where order can be totalitarian or anarchic as he interprets it. That interpretation being the absence of arbitrarily imposed order established by fiat by a ruling cadre. And that is the major thrust of the book: whatever we may be told, authoritarianism is not the alternative to chaos; it is in fact a submission to chaos, in that one fears it so much that any variation in behaviour is seen as chaos spreading.
So, basically, come to V for Vendetta for the story (which is great) and the artwork (which, in its austerity, is amazing), but expect to have your mind broadened by the dialectic that is at the core of this great book.
