For me the only things keeping ROTJ from being PT level bad are Ian McDiamid and Mark Hamill.
I think the PT and ROTJ could have been good films equal to ESB but George’s yes men ruined it. He needed someone to counter his goofier ideas and his apathy to quality after things got really rocky with Marcia.
Star Wars made serious toy money (nothing wrong with that) but the merchandise came from the first two films it started to star in the third one and took over the prequels for which it was the main reason for those films to exist.
I think there are some good things to be salvaged from ROTJ and the PT it’s why I’m looking forward to them getting the Adywan treatment much more than the first two projects.
They are the most broken so there is nothing to be lost by trying to fix them from an alternative fan viewing perspective. I would preserve the theatrical cuts of all the movies because of their unique cultural impact. I’d preserve The Room for much the same reason.
