The theatrical bonus DVDs were actually made from the same masters as the laserdiscs (this is why they are presented in a 4:3 letterboxed ratio). I can appreciate that the sheer increase in resolution may be enough to win over some people, but the progressive number of changes to these films over three major revisions, has made a massive change to the pacing and basic cinematography. I bought the 2004 DVDs, but I had already decided to try and avoid even reading about the blu-rays, because I knew there would be more potty changes. George Lucas was the man who in the 80's stood up and appealed for the preservation of the original versions of films, and to prevent them being significantly messed around with forever. Charlie Chaplin did the same thing to many of his films for the fashions of the day when he re-released, and it did those films no favours.
I mean, you have to wonder what he will do next time? The things he has been doing are so ridiculous. Vaders 'nnoooo!!' is potty. I mean, why worry about 'fixing things' like R2D2 hiding behind rocks in Star Wars, when in the next film Luke Skywalker passionately kisses his own sister, and then in film after she tells him she knew he was her brother all along? Why didn't they fix that? Or why make a film where with 22 years prior knowledge of the Return of the Jedi script, you let Leah be dragged away from her mother within 5 seconds of her birth, even though you have previously indicated that she knew her mother during her childhood? All these daft superficial changes to make it more "real" just seem to do more and more to destroy the suspension of disbelief. And don't get me started about the Jabba scene in the first film, that one makes no sense at all. It duplicates most of the dialog from the Greedo scene! You have to cut most of the Greedo scene, or the Jabba scene has to go altogether, one or the other, you can't have both!
I tell you, one of these days, Luke will pull that mask off and it will be Hayden Christensen under there.
