The dear old BBC has weighed in on George Lucas's latest changes to Star Wars in a lengthy and thoughtful essay by Will Gompertz entitled, "Why Star Wars should be left to the fans". You should read the whole thing, but if you can't be bothered here's the stinging conclusion:
In short, the artist is probably not the best person to judge their own artwork, and - in my view - Lucas should probably listen to his fans and allow all versions of the films to be seen (even if that means spending a few quid digitising the originals).
Now there's a great idea. How great would it be to have the original three films, as shown in cinemas, on Blu-ray? Lucas could make even more money, although at this point I am really not sure that money is what motivates him.
