INVAR - Those points you make about the movie are very important indeed and I've also followed those since day one and been fascinated by them.
The opening crawl, Vader and Emperor's communication and finally Luke and Vader's confrontation are for me the three most important parts in what the the psychologically inside the story is all about.
They also play a huge role in the development and understanding of Vader's character arc.
I must admit though, the line "The young rebel who destroyed the Death Star" is pretty bad, for me at least.
I feel as though the original dialogue is all that is needed, so I'll be very happy indeed if no change is made there.
Nice to read your thoughts on all that though :)
