Star Wars was good because of Lucas' noninvolvement on the original 3. He didn't do the editing and they were good.
Now look at the new ones.
Agreed, the big three, Star Wars(good), Empire(best), and RTOJ(ok out of the 1st 3), totally blow away the new ones. Even with all the flashy CGI effects. Something about real models that makes it that much more enjoyable.
