Of course, on its own, the original Star Wars is a great movie that doesn't need any changes. I don't think a person on this board would want to see it disappear forever, even if Lucas had released Adywan's edit in '97. No one here is looking to take away from its greatness.
Mojo, I hope you are not falling into the Lucas fallacy that there can only be one version of Star Wars. No one here wants to throw the original Star Wars out with the trash, or to say that the Starkiller Ranch version of Episode IV (if it even gets made) is better than the original. Star Wars is one of the best movies ever made in the history of cinema. We only want to create an alternate version that blends better with the entire saga. And we can only do so much with what we have.
But when you are done filming your own prequel trilogy, which matches the OT in terms of continuity and tone, please let us know.
This place is a playground of ideas. I respect yours, but I disagree.
