Don't forget he did not just add cgi to star wars trilogy and destroy the originals. He has also ruined THX 1138 with no original being even on dvd, he added cgi to the opening of graffiti.
He even added cgi to the broadcast of Raiders of the Lost Ark. True in American Graffiti and Raiders it is a single shot replaced, but the tinkering was neither wanted or needed.
Never mind the Digital scrubbing or dvnr Lucas has done to the DVD versions to remove the film grain to Make the movies look like they were shot on HD video and not film. Also recolor grading the films.
It is so stupid that the only non butchered versions exist on Laserdisc and are non anamorphic.
