I really enjoyed V for Vendetta a lot. Great movie. I went in expecting excellent action scenes and a reasonably interesting story, and ended up getting reasonably interesting action scenes and an excellent story. If you can at all avoid it, though, don't read any reviews. Stay away from 'em. Just see it; you know you're going to anyway. I skimmed a single review and it ruined the impact of one of the most important parts of the movie.
If promises of a great story and cool action scenes can't interest you, I can also promise you an above-average number of lesbian scenes. You know, just in case that tipped the scales.
