Jabba-wocky, I've tried several times to make a similar point regarding Force attunement. From an OT-based perspective, for all we know the genetic component could simply relate to heritable personality traits, the presence of which would make one a "better" Jedi. Good luck trying to convince others of this. I also got a similar reading to yours on who the Jedi were, from the OT. I think it's a valid reading, though as Lucas was heavily inspired by materials like the Lensmen stories, I suspect the PT Jedi are actually close to what he 'always wanted.' Even if what we read out of the OT seems different and works just as well. Though, I don't agree that ESB is not enjoyable. For me, the atmosphere of the film - conveyed by the design, the score, the shot composition, the colors, lighting, the particular mix of humor and seriousness, etc - makes it a favorite.
