They are not all shit, only about 95% of them.
Actually, I would say that the majority of them are not shit. The majority really are subtle little things like removal of matte lines, cleaned up effects, subtle enhancements like the Cloud City Windows, continuity fixes, etc. If that was all the Special Editions were I would be all for them, but the minority of changes that are big and noticeable are unfortunately so bad that they simply can’t be ignored.
