ANH:
1. I did like the new approach to Mos Eisley. It did open up the city much more and showed it in a grander scale. It could have been done better but over all I liked it very much.
2. The Han and Jabba scene. I have always felt that this needed to be there. It was one of my favorite scenes in the book. True, the digital Jabba didn't look that great and it totally needs improved but overall the scene worked for me. Even Han stepping on the tail. It's for the kids so I can live with it.
3. The added Falcon taking off from docking bay 94 and landing on Yavin IV. Both seemed to be executed very well and it did add a bit more demensin to those scenes but over all I think they were really not needed.
4. The X-Wings and Y-Wings taking off from Yavin IV. This I thought was a huge improvement over the original.
5. The removal of the cardboard people. However, being a nut for film errors I think this one is just hilarious.
6. The Biggs scene. Loved it, loved it, loved it.
Most of the other stuff, Ben's house, the sky, the Sandcrawler (which I didn't know about until I read it here), and Han and the Stormtroopers I really don't have any feelings one way or another.
Empire
1. The snow battle and removal of the transparent cockpit. Being able to see the battle through the snow speeders cockpuit clearly was a marvelous improvement.
2. The approach to Cloud City and the Cloud Car fly by. I liked these along the same lines as the Mos Eisley stuff.
3. The windows. However, they need to be a little more consistent. ONe minute they are there and the next they are gone. Let's make up our minds shall we?
The wampa thing isn't a like or a dislike. I can live with it but it really wasn't needed. Some of the other small changes I'll have to go back and compare the original to the SE to judge.
Jedi
1. The Bantha herd. I though this was neat and unexpected.
2. The end music but not the celebration scenes.
Most of the rest of the changes to Jedi I really didn't care for or they were in my opinon just not needed.
