the truth of the matter is... the prequels ruined any consistancy that the OT had!!
BOTTOM LINE!!
i don't care if you dont agree because it is a proven fact that everything that came out of the prequels has made lucas go back and alter his OT...
once again if that wasnt true then he would have wrote the story around the OT and not the OT around the PT.
so fact is that Lucas never had an original vision about 6 movies...
no way in hell!!
you can say what you will but he didn't.
did he have an original vision about the OT itself.
in a way yes. but as others have pointed out, luke and vader father and son and luke and leia brother and sister prolly were added in there during the process of filming the trilogy.
