Way to throw him under the bus for no reason. I think even King Kong features better compositing than Star Wars... I'm actually not against cleaning up things like the speeder shot. From what I've seen the drop of quality is genuinely apparent and not just a figment of Lucas's imagination. Sure, you might not notice it on a release print - but, honestly, what official restoration comes from one of those? This isn't replacing the effect we're talking about. We're talking about presenting it as best possible. So I say DNR the hell out of scenes like the landspeeder one, so long as you don't touch it any further. Maybe that makes me less of a purist than I thought, but cleaning up a scene (in moderation) like that would be a far cry away from removing wires or mirror reflections.
