I'm willing to buy that the OOT Star Wars was only 25% done. But the changes he made affect only about 2% of the film. Does that mean that the DVD Star Wars is only 27% done? When's he gonna do the 73% that's still missing? What, conceptually, is still missing? What's left to change? The performances? The music? The production design?
If OOT Star Wars was only 25% done, that means that the "real" Star Wars is more unlike the OOT than like it.
