James Wolcott Gives it Two Fists in the Air (mild spoilers behind link):

...when it was over I knew it was the movie our post 9-11 minds craved and unconsciously had been working towards, a movie that conjured the fear of terrorism and repression and didn’t just tell us how we got into the Orwellian predicament we’re in (terrain already attacked by Fahrenheit 9-11, Syriana, Why We Fight), but made the imaginative leap that would lift us out of the news, out of the political present, and stand up to that fear—face it with fury and compassion.

...

And make no mistake V for Vendetta is fun, dangerous fun, percussive with brutality and laced with ironic ambiguity and satirical slapstick (a Benny Hill homage, no less!). But gives the movie its rebel power is the moral seriousnessthat drives the action, emotion, and allegory. That’s what I didn’t expect from the Wachowski brothers (The Matrix), this angry, summoning Tom Paine moral dispatch that puts our pundits, politicians, and cable news hosts to shame. V for Vendetta instills force into the very essence of four-letter words like hate, love, and (especially) fear, and releases that force like a fist. Off come the masks, and the faces are revealed.

I wanna see it.
