With the rapid growth of technology and materialism, it's hard to stop and see what's happening because, come on, with all the luxury and glamor it brings, we're just there to try enjoying the ride!
Movies like this, the idea of what the world will be like in the future... a more standard, structured, technologically superior society where no one is much more than a robot, unnaturally suppressing humanity is just something to stir the mind into realizing and understanding the present. The present paves the future.
It's a good movie, and the Ethan Hawke/Jude Law/ Uma Thurman classy combo is deadly, but if you want something even more in-depth to the thought... go read Aldous Huxley's 'Brave New World.' That's sure to scare you!
