Could it be that George was telling the truth when he talked about his "original" vision???

Isn't this less "Random" and more "Theatrical Cuts vs Special Editions"?

That said, I tend to mostly believe that George's original vision for the trilogy was godawful, and it was only through the fortunate graces of pragmatism, budget and time constraints, technological limitations, and George not yet being considered infallible by his co-creators that we actually ended up with the great films they were. If anything, the Special Editions put an underline under Marcia Lucas' Oscar for Editing, because we got to see what happened without it.

But he also makes it up as he goes along: consider Luke's scream or lack of scream falling into the chasm in Empire. Obviously his original vision, if it even exists, is malleable.
