He owns the copyrights and nothing we say will change his mind.
He is he most egotistical of all filmakers, he believes essential in a creators rights which i do also, but at expense of destroying the only good films he ever made.
Thanks to his ego i cannot watch decent original versions of star wars oot trilogy, thx 1138 or American Graffiti. I can watch the indiana jones trilogy pretty much untampered with and Willow but those were not directed by Him. Neither were Empire and Jedi but Lucas would disagree.
He will continue to make Bad Prequel stuff and cgi farce Indy pictures because they make money.
