I must say, Adamwankenobi, this is quite a revelation, but when I think about it, I'm not surprised at all. We don't expect you to watch these films and think 'damn, the effects on the O-OT are so much better'. We expect you to understand why we are angered by the storyline changes, though I'm not sure you'll be able to do that, seeing as you've already formed your opinion without having seen it.
But most of all, I hope you can appreciate that things like cleaned-up frames and updated effects could have been achieved without interrupting the flow of the story; without changing the story; and I'm pretty sure, without pissing all of us off. I would have NO problem whatsoever with a CGI cloud city, with a CG battle of Yavin, re-rotoscoped lightsabers, ANYTHING cosmetic that doesn't ruin the story or the characters, but what GL has done is completely different. He doesn't let us have the cake and eat it too. We're expected to eat the cake, even though we only like the icing.
For the record, the effects of the O-OT still hold up in my books. A fully restored version of the O-OT would still be considered impressive by a lot of people.
