Tron

                  In Tron, the government is exposed as a corrupt organization that host these immoral tournaments. To begin with, the government had the main character's father assassinated simply because his beliefs conflicted with the views of the country's major technology company. The company, in a way, resembles Apple. The government is then found to hold these contests of speed and strength where people put their lives on the line. The director is attempting to get a clear message to the audience. The message being that we can't toy with people's lives, no matter how powerful our government is. This would cause our civilization to backtrack and wind up like the ancient Romans and the coliseum where people had absolutely no morals.
                  The Director gets this theme across with all the dark imagery. The setting of the movie starts off in one place and switches a couple of times throughout the trailer. In all of the places that the trailer takes place in, all of them have this dark mien where everything simply seems to be wrong. The director does this to represent the lack of morality or light in this society. If we continue to forget the fact that we're all equal and that no government can thrive off of immorality, our future will be a dim and unhappy one.
