I'd like to say one more thing that I just remembered:

When I was watching Episode I & II, I hardly had any idea what was going on. Episode III was easier to understand, and I always knew what was happening in IV, V, and VI.

I remember my first reaction to the podrace scene, I thought, first of all, IS THIS SOME KIND OF RACE? FOR WHAT? WHY IS THIS SO DAMN LONG? After I watched it I thought it was a very boring movie and was too "political".

Also in the Han/Greedo scene from Episode IV, right after Han shot Greedo, I thought, "What just happened?" I can't explain what I exactly mean, all I know is that there was an explosion and the green alien is dead.

I re-watched Episode I last week, and I think it's a lot less boring if you actually know what's happening. But the only way in my view to make Star Wars truly perfect as a saga (not just IV, V, and VI) is to re-do I, II, and III. If I, II, and III was done with a different director, then the SE would have simply been better image quality (and other minor things that wouldn't have caused controversy)
