It's kind of similar to my reaction to the Matrix ... the original Matrix was great all by itself. I was excited about the sequels, but they turned out to be a disaster. So now I just pretend they don't exist, and enjoy the original movie for what it is.
The difference with Star Wars is that I do enjoy the Prequels somewhat (though I have to grit my teeth to get through some parts), so I don't want to pretend that they don't exist. And I really don't mind having a "Prequelized" version of the OT to go with the Prequels. But I still want to be able to enjoy the original trilogy in all its unaltered glory as well.
What I really want is the Alien Quadrilogy treatment -- a nice set with the original and "director's cut" versions of all the films. But I'll take what I can get ... which means LaserDisc-quality bootlegs for now.
