i can live with effects changes just as long as their not distracting to the story/dialogue (ie. luke and obi wan being interrogated by the stormtroopers on tatooine) and they have to look like they fit with the look of the film...

so i dont mind the space battles... i can even live with the small eye candy like the batha's walking across the dune sea in ROTJ...

but i still despise the entrance into Mos Eisely, Cloud City windows, jedi rocks, end celebration and so on...

but dialogue changes are just not necessary whatsoever!!!
