Lucas says in one of the DVDs, I forgot which one, that people always say to him, "Oh, you should have kept that scene in the movie! Oh, the movie would be better with this scene!" And he says as much as he wants to keep them there, they gotta' be taken out. They're unnecessary padding, that make the movie fat and bloated. That's the beauty of DVDs: we get to see the deleted scenes on their own, separate from the main movie, where they belong.
