So.
Although the government of today (In England) is a progressive bureaucratic creeping state of regulation and control, V for Vendetta makes the evil government a Christian Dictatorship? Yeah...that's a believable outcome.
The Hero tortures the Heroine to get her on his side in the grand fight? And he's the good guy?
The glorifying of Guy Fawlkes for his attempt to blow up parliment? What?
V for Vendetta is a stupid movie.
If you want to see a great movie about standing up to an evil state watch "The Lives of Others" A movie based in a believable world, one that really exists. Set in the ex-communist East Germany. It is a beautiful movie with sadness throughout but redemption at the end. Including bravery and doing what is right.
