Ah, another thread that needs to be revisited. I don't mind some of the changes to the DVD after seeing ROTS, but I still had Fett's voice change (and complete lack of enthusiaism by Morrison in the voice dialogue), the new Jabba music sequence, and, of course, Greedo!
Surprisingly enough, seeing Hayden in the end of Jedi didn't bother me as much as I expected. You get more of an emotional sense of closure, having seen Hayden turn to the Dark Side. He still has kind of a creepy grin on his face, but the idea works. As with most of Lucas's films, the audience has to do most of the work, but ultimately, we have a hell of a lot of fun doing it!
