Saw the movie. Clearly has the 9/11 govt conspiracy feel. The movie trailer shows Parliament blowing up at the end so that's no secret. It's a little sad though to posit that all the glazed-out citizens who'd sheepishly given over their freedoms now blow up an institution dating to the mid-13th century--and return to anarchy.
I don't favor totalitarianism over anarchy, but it's a well-known fact that most societies do.
My biggest complaint about the movie as entertainment is how impossible it is to identify with a person in a mask for the whole picture. It's creepy and cold and alien--sort of like watching a robot.
