Well, I like them, but only because they are so much less mangled. The theatrical pacing and performance is just more enjoyable overall. And that's what it's about isn't it? How enjoyable the movie is to watch. I don't know why they substituted lines in the SE with poorer versions that obviously had more takes done for a reason. The sound mix also just seems more dynamic than the almost flattened newer mixes that, for whatever sound quality that is gained is completely discredited by lack of any effort to hide transitions between good quality and bad quality takes. Matrix decoded 3 channel surround sounds almost as good as 5.1 too.
The scenes that were put back in were obviously cut for a reason. The problems the scenes had were problems that were solved 30 years ago. The solution became the theatrical cut. Going back on that means introducing new problems and destroying the solutions. And the new effects don't seem to do much good either, there's a few cool things but mostly these new scenes don't replace old ones that don't work. Most of the time they actually seems to be replacing exactly the effect shots that did work while for some incomprehensible reason leaving the ones that simply just won't fly. The biggest crime of the special editions is ruining the pacing that was so carefully put in place all that time ago. The very thing upon which the success of such a swashbuckling film rests.
On the other hand they did take the fading film and made it look absolutely amazing. The Special Edition is probably the best quality transfer of the OUT you'll ever get anywhere. The question is whether or not the digital master is unmangled enough to support reconstruction of the original film. There's quite a few of the effect shots that apparantly irrepairably destroys the original content of the scene.
And that's what really gets to me with these. The low resolution, heavy grain, ghosting and ... ugh, aliasing is very distracting. At least ESB seems clean enough to be visually enjoyable. Not sure about ROTJ, but ANH is a disaster.
