The culture has pretty much already came to the consensus the prequels sucked, and that the original trilogy is a classic. And there is nothing Lucas can say to change that.
He can talk about how the prequels made him a billionaire if he wanted to but that does not make them great films.
The bayformers films made tons and are garbage, by Lucas own way of judging things those must be great films too.
Unless how much a film grosses is somehow more important than storytelling and character.
