V for Vendetta - 8/10
Basically, it was entertaining. I really enjoyed the matter-of-fact and aloof nature of the title character, as well as his quirky literal personality. Portman delivered a solid performance and looked surprisingly hot after she shaved her head.
The plot, while it clearly wanted to make the viewer think, had elements which I found too absurd to effectively suspend my disbelief. I would have enjoyed it more, and it probably would have made me think more about the subject matter, if the "bad guys" weren't so purely evil. They seemed more like caricatures than characters...however, it's based on a graphic novel/comic, so perhaps that was to be somewhat expected.
That being said, there were really sweet visuals, great dialogue, and it kept my attention throughout.
