The Jabba scene would have been great IF THEY HAD REVERTED THE GREEDO SCENE TO ITS ORIGINAL DIALOGUE.
With the removal of the Jabba scene, they added a line RIPPED DIRECTLY FROM THE JABBA SCENE into the Greedo scene, and altered Greedo's subtitle dialogue to cover the bases that were left open with the removal of said scene. But when they added the Jabba scene back in ... they kept the Greedo scene's dialogue the same, which made the Jabba scene highly redundant.
The Biggs scene is good, except the wipe that cut the "father" reference is a bit jarring and shortens the scene too much.
Long intro to Mos Eisley wasn't really necessary, but I could have lived with it if the slapstick humor hadn't been there.
What new sandcrawler scenes are we talking about here? The small amount of new FX? Not bad IMO.
