Personally speaking, if all Lucas did was "clean up" the Original Trilogy's FX to make it more palatable to the current generation, then I don't think we'd have much of a problem. Clean up the lightsabers, smooth over the mattes, get rid of the landspeeder cloud.. I'm not saying I would like it, but these are changes that I would NEVER be vocal about.

But when that senile old bastard starts screwing with the actual story, then he's naturally got a problem, especially as all of the story/scene changes and additions (Greedo shoots first, Wampa munches, and munches, and munches..., "Hayden Ghost", Han blabs with Jabba over nothing, etc.) are absolutely terrible, self-serving, fit-the-crappy-Prequels horse-shit, and shows that a senile old fart should never story-edit his younger, more talented self.
