Its how I put it before, the feel has changed. The focus is different. Whole scenes are changed. To some, Han Solo was changed in a mere two seconds. There's now things one never thought about thrusted into one's face. There's so much stuff in the background of Bespin, that's all you look at. Heck, I'm still staring there when I watch the OT because of it. The new establishing shots put greater emphasist on otherwise unimportant things. The Jabba scene delays the plot and damages Jabba's character. We see celebration scenes that make it look like the Empire was hated by EVERYONE, with planets that don't even care taking part in the festivities. We have a stupid dance number that doesn't even fit with the film. The Vader shuttle scene in Empire is among my most reviled. The music is interrupted, the tension destroyed, you're sitting there cringing at every hit the Falcon takes, wondering how they'll escape, than suddenly the scene changes. And for what?! Vader landing on the Executor. George is so focused on hammering every point home that even that isn't left to imagination. What's next? A conception scene in ROTS to remove any doubt that Luke is Vader's son? If you think the changes are so diminutive, why were they made? If it changed nothing, what was the point? If I weren't so big on SW, and a fan of the EU, I probably wouldn't care as much. Lucas can do as he pleases, but the SE isn't canon in my book.
