I always though that the idea to do prequels was a bad one. Most obvious is the fact that it never really works because the technology is so much more advanced in the prequels that it destroys the continuity.
I would have rather seen an approach similar to "The Godfather 2", where it was primarily a sequel but they used flashbacks to tell the story of Don Corleone. I think it would have been far more effective if Lucas would have kept the story moving forward, while using flashbacks to tell the story that led up to the present. With the Godfather series, you can watch them in order and it doesn't seem strange. Not so with Star Wars.
Just my humble opinion, of course.
