I’d say that overall the positive changes are countered by the negative changes. I hate the dialog changes and the wampa scenes were not needed. I like Ian as Emperor, but they shouldn’t have changed the dialog. Vader already knows that Luke is his son and he has already mentioned Skywalker by name earlier in the film so Palpatine pointing it out is rather stupid. Some of the extra windows in Bespin are cool, some are stupid, and some are inconsistently applied. I did love the extension of the ending and thought it built more tension and was an improvement. But overall the SE is no better or worse. It is mostly because the core of the film is unchanged and it is mostly just corrected or enhanced FX.
