Anthony Parisi has a well-written essay called Revisiting The Prequels, which asks for people to give the films another look:
The six films form one larger epic that is constructed like a piece of music. The narratives are light on plot and characterization, instead built on archetypal themes and psychological motifs that reverberate throughout the six episodes. Lucas often talks of approaching Star Wars like a silent film where the sound and the effects “are just a part of the musical composition to tell the story visually rather than through a lot of heavy dialogue.” This becomes more refined in his work on the prequels, where everything from mirrored plot points to spaceship designs are carefully placed to echo and build into the original trilogy. Lucas is a firm believer in “pure cinema.” His story is in the images and every image tells a story.
