I bet most people here would have to agree with Will. I mean, a lot of changes can be explained (reasons of continuity between trilogies being the most obvious one), but I just can't stomach some that have been pointed out by this great article (and comments by people like you): the mismatch between CGI and the classic "puppet" approach (an aesthetic horror, and error, in my opinion), the HC ghost in ROTJ that completely de-humanizes Darth Vader (and nullifies the unmasking scene, clearly one of the most poignant scenes in all of SW), the relative uselessness of the Vader-Emperor dialogue change in ESB (which dangerously hints at Vader's "fatherhood punchline", the dramatic climax of the film), the ridiculous color changes of certain specific lightsabers, the softening-up of Solo in the Greedo duel, and most importantly (although not very often discussed), the all-too-fast pan-galaxy celebrations at the end of ROTJ that diminish the vision of both a well-established Empire (remember the power given to the regional Governors by the Emperor in ANH?) and a small-scale/independent/against-all-odds Rebellion. I just can't see how this really helps the overall STORY, even if you DO like the PT (or certain less important changes in the SE).
