You also said they are "just movies"? That implies they have no more importance or value beyond the latest box office spectacular. Are people going to waxing nostalgic about being at the first showing of Transformers 3 twenty years from now?

When people start to think Jabba was created and inserted into the film in 1977, it's unfortunate. Thirty years from now, how will kids know what they're seeing isn't the original real deal? If I watch a film made in 1939, I have a reasonable expectation I'm seeing what people in 1939 actually saw. That requires some honesty on the part of the studio and the filmmakers.

There are THX-1138 reviews on the web that seem totally oblivious to the massive changes done to that film. And Lucas has deliberately not talked about the CGI additions. Re-writing the history of a movie begins with omission.
