I'm pretty torn on this. A simple scan of a cleaned print, with proper color timing, is our goal here. But I admit I'd be disappointed if there were visible matte lines (boxes) around ships. I don't remember ever seeing those in a theater in 1977. They would take me out of the experience.
So I guess I'd like to see both versions: a straight scan as well as a version with recomposited ORIGINAL elements.
Ultimately, I want a version of Star Wars that I can watch without being distracted by crap that's not part of the movie. I want to be transported back to 1977.
