Disney does have a history of going for the lowest common denominator with people. Who is the most recognizable figure in all of star wars, and even the most recognizable sound in all of star wars? Darth Vader, his helmet, his force choke, the sound of his breathing apparatus, even his theme song are very clear in peoples minds. If there is something that Disney will reuse, that they should never touch, is Darth Vader. His story is complete, the entire saga began with his discovery, and ended with his death. Anything after episode 6 that involves Vader is a travesty.
