The lone man single-handedly leading a group of oppressed people against an overwhelmingly powerful government using only kung fu, homemade explosives and a few videos is uniquely entertaining. The movie is exceptionally well-done and strikes a similar chord as The Matrix, which I watched 9 times in the theater.
Guy Fawkes ostensibly became a member of this plot to protest a lack of religious freedom. He failed because he failed to apply the principles of his religion to achieve that goal. Jesus was a clear advocate of nonviolence as a means of protest. The idea of murdering even the worst oppressor would have been abhorrent to the founder of Christianity.
The problem with using Mr. Fawkes' likeness as a symbol of personal freedom is that he symbolizes not freedom from oppression, but rather enslavement to the very forces that have dominated mankind's history of violence, war and thievery for thousands of years.
In the words of Gandhi, "An eye for an eye leaves the whole world blind." Guy Fawkes was truly blind. He failed to recognize that the world is not composed of action heroes and evil villains, but of human beings; and that if effective change is to be achieved, it will be not through death and destruction, but through increased communication and empathy with one's fellows.
