Also from that article:
"... if we were going to take this movie and cut it up into 2,000 separate pieces, we had an opportunity to upgrade what those 2,000 separate pieces are. It seemed like we had a perfect opportunity to go back and create a cleaner, sharper and purer version of the movie."
It's kind of discouraging to think they had the opportunity to rework the film and they didn't fix any of the big problems. I guess Lucas really liked the way it turned out, despite all the criticism??
