Well, the second trilogy was a significant reversal away from a smaller personal story (Luke's destiny stuff) set against the backdrop of a Galactic Power to a Galactic Power story (the major story in the prequels is more the engineering of the fall of the Republic) with the personal Anakin story serving as the backdrop.
