Apparently V for Vendetta was a highly successful comic book at some point. The movie, as I understand it, didn't do well. When you see these giant budget, action movies bomb you can usually trace it back to a property that did well in another format or copying the success of another movie. You can kind of hear the pitch meeting for V for Vendetta -- "Yeah, like Spiderman only edgy. Comics are hot and have a built in audience. Spiderman, Batman, all did major numbers."
I made the mistake of seeing V FOR VENDETTA on the recommendation of a co-worker. It was deliberately insulting to Christians while glorifying everything from homosexuality to terrorism. It included some scenes so over the top in their anti-Western hysteria that they had to be deliberate (e.g., a homosexual preserving a Koran so that its beautiful art and poetry wouldn't be destroyed by dictatorial, rampaging Christians). If Big Brother in 1984 were to make a film, V FOR VENDETTA would be it.
