Well, for me, this goes deeper than the visible physical manifestation of all of this stuff - and includes the general sentiment.
For example, From Peecher's book...
Luke has come back to the Death Star from Endor to force a confrontation with his father. This is the big scene. Richard Marquand describes a George Lucas insight into this scene: "There was a feeling I had that I would like the fight to be bigger than the fight in Empire. And then George said that it doesn't have to be bigger, because basically it can't be.
George is very blunt. He said: 'It's just a couple of guys banging sticks against each other. Don't worry about that. It is bigger because of what is going on in their heads. That is what makes it bigger.' That was nice, because then I saw exactly what he meant and I think up to that point I had missed a trick."
Regardless of what you think of ROTJ as a movie, it is obvious Lucas still grasped the value of 'less is more' even then, wheres now, it would seem, does not trust the audience enough to 'fill the blanks' and be informed by what is happening inside characters' heads - so he adds an ugly big "Noooooooo!" into this key scene.
But really, how could we ever be in a position to second-guess Lucas' "original vision" after this?
I mean, the Ewok designs by Rodis-Jamero, Johnston and McQuarrie that were approved by Lucas (and in my opinion, the most aestheitcally pleasing designs, despite some of the other designs by those same artists having irisis and pupils) looked like the versions that ended up in the film. Surely the old Fabulouso stamp can't have been brandished accidentally?
