It doesn't matter where you kick me, I'm still coming back for more

This is probably the primary reason why George Lucas is able to do what he does. Some of the changes that have been made to the DVDs (and most of the changes in the Special Edition which are thusly inherited) feel like molestations of something that wasn't really broken, and in many cases seem like Lucas doesn't understand why these films are actually popular. Though it is significant that The Empire Strikes Back has remained pretty much intact across the two recent incarnations, the largest change being the insertion if Ian McDermot as the Emperor instead of the old lady they had orriginally used. This is a change that not only makes sense, but looks a lot better than the orriginal. I'm undecided though about the change in dialogue as I havn't seen it yet.

Still, Episode III...
