And I can quote word for word what Go-Mer's response to this post will be.
Lucas changes whole scenes, and is very instrusive, and overall makes his movies worse. Jackson just erased a car in the background, that you have to be watching carefully for to begin with, and it is an improvment.
Lucas changes weren't intrusive at all, and just helped clean up the films. How can you say erasing a car is less intrusive than addding CGI dancers into Jabba's palace and replacing the whole scene? It all helps the films flow better. I love Lucas. I love Jar Jar. I think Anakin is the coolest chracter ever.
Etc, etc...
