That lady is full of shit. V for Vendetta was a GREAT movie. Why shit on it in order to create consistency with your "every Alan Moore movie is garbage" theory. It's not the case.
V was good movie (with some bits that were rather cringe-worthy to British watchers) but it doesn't come close to the original book, so in that way, she has a point. It's not as big a traversty of an adaptation as LXG or From Hell, but its definitely not Alan Moore's vision of V for Vendetta.
