It cannot be "saved" or "salvaged" or "restored to former glory" simply because the original 3 Movies live in our childhood memories as these amazing experiences and fantasies and colourful images. No one can create a movie which will compare or surpass your childhood memory.

Even with the argument that the original 3 Movies are still good if one watches them again now, you will just remember or re-live your own personal childhood memory.

Are the 3 Original Movies better than the 3 newer ones? according to my 5 year old son yes - but then again for him it is Darth Vader that sells it. Besides Darth Vader it is Yoda for him in the 3 new movies he loves. Will he think the original 6 movies are by magnitudes better than Part 15 - 18? I am betting everything that he will feel that way.
I am still looking forward to watch every single one of them together with him, because we love the Star Wars, each for his own reasons.

And this sentence illustrates perfectly the biggest issue with the android platform.
