This question tugs at me on many levels. First, it is wrong that someone would take a classic work of art and change it 20 years later. That's why I resent the SE... it represents an artistically repulsive act. Second, I don't think that the prequels are very good movies, so modifying the OT to make it fit better with the prequels is - backwards! It's like repainting your Porsche to make it match the color of your Ford Gremlin. He ought to go back and redo the prequels so they flow better with the OT (and so they're less silly, but that's another issue).

Frankly, I think the whole problem started when he decided to make Vader be Luke's father. Too coincidental, and too complicated. From that point on, the only way to make sense of everything is to make changes. And in the process, the original Star Wars ends up being changed into a movie that just isn't as good as it was originally.

Now, that said, I watched the SE movies three times in the theatre, each. I didn't like the changes - it was all too painfully clear why the restored bits had been left on the cutting room floor by a younger and more visionary Lucas. But I went again and again because, in spite of that, it's still fun seeing Star Wars on the big screen again after all these years, and being a high school kid again.
