Achieving a complete understanding of life may be as impossible as it is alluring, but still we strive toward it.
What's certain is that learning about life is inherently subjective. Any attempt to paint the entire picture of reality from a single viewpoint is sure to result in a mere self-portrait of the source, and not a complete representation of the whole. But with care an individual may understand one's own life well enough, and therefore by studying enough subjective perspectives we might distill the fundamental truths needed to build a realistic worldview.
The poet William Blake once prompted us "to see a world in a grain of sand… and eternity in an hour." Perhaps with the aid of these ten movies we can see our lives in a reel of film, and existence in two hours.
