I went, I saw, I sighed. V for Vendetta does not deliver the goods. Wired Magazine puts it nicely:

V for Vendetta“Hollywood, with its congenital fear of alienating anyone, manages to dilute the comic book’s radical, complex vision. What’s left is a fuzzy, pandering film. What are its lessons? Totalitarianism is bad. People power is good. Unless you aren’t quite sure where to stand on the whole Hitler-Nazi-Holocaust thing, Vendetta is unlikely to evolve your worldview.”
