Matrix: What if we are all living in a simulation and don't know it? What does this mean for the human existence and how we perceive it?
Animatrix: What if we get so smart we build machines that are so advanced that we can discriminate against them? What happens when humans create life and expect that life to remain servile?
The Matrix Reloaded: What if we fleshed out this world to show multiple societies co-existing, although not entirely peacefully? What if we throw a bunch of rehashed dialog from other science fiction films? What if we change the style to be slicker? Can we pull it off if we inject just enough substance to make people want to watch a third movie?
The Matrix Revolutions: Take the wheel, I have no idea how to end things but there should be some massive fight scenes. Ka-CHING, baby.
