I’m actually quite fond of three changes:
Han Solo’s charging into a room full of stormtroopers just makes that sequence even funnier to me.
Ian McDiarmid’s Emperor being placed into ESB was great.
I am fond of Victory Celebration over Yub Nub. Though I loved Yub Nub as a kid, I like the emotional impact of Victory Celebration now–I even like the galaxy celebrating scenes that they added.
