After reading what he would've done with RotJ, it would've been far more interesting. Probably less compelling to the small child me, but far more interesting.
Most of us TRF'ers aren't even old enough to have been around when the original trilogy was showing in theaters, but we still love those films passionately. It's easy to look back and say, "If we'd done this thing differently it would have been better." But such postulation leaves aside the adage, We-Are-What-We-Eat and in this case what that means is, sure, maybe things could have been done differently and it might have been a better film... but then again, it might not have and those changes for the so-called better could have utterly changed the history of Star Wars to such a degree that we, TRF'ers, might never have come together because the legacy of Star Wars might never have been born. It is impossible to say.
Maybe if someone had shot Adolf Hitler in the brain back in '35 we'd never have had a World War II and millions of people might never have died. Or, maybe, something far worse would have taken place.
We, as humans, readily criticize the past often failing to realize that the past is responsible for the present.
However; I would gladly suffer those possible changes, had someone been at George's side during the prequel days, slapping him with a tuna every time he did something stupid...
