I just saw the movie last night and I really enjoyed it! Yes, it is easy to see how some people could take this movie the wrong way...but I simply cannot see how this movie glorifies terrorism (which I of course, utterly despise).
I think that the simple message at the heart of this film is that people must fight against oppression. That's exactly what V is doing. However, nothing should really be read into the fact that he's fighting against the British government in this film, because as I'm sure most people can see, this government is NOTHING like Tony Blair's government (or the US or Australian governments either, for that matter). It's much more like Nazi Germany, the (former) Soviet Union, East Germany, North Korea, China, Saddam Hussein's Iraq, Iran, or Afghanistan under the Taliban. That being the case, I'm a bit mystified as to how some critics have managed to label it an anti-war film - as its central theme would seem to lend support to the idea that such oppressive regimes should be destroyed and freedom allowed to flourish...
All that Alan More has done has asked WHAT IF Britain became a fascist regime in 20+ years time. I don't think that anyone could really try and say that Britain is actually like this now, in any way, at the current time. (though I'm sure there would be some who would like to see it this way). Sure, V might be called a terrorist, but just look at who's calling him a terrorist (the fascist government). I wouldn't take their word for it
In short, this film is about as accurate an account British society today as the George Orwell's novel 1984 was with regards to how things actually were in 1984. Nonetheless, it's a great spectacle and has a bit of an unique angle to it.
