The more you analyze the Jabba scene in ANH, the less sense it makes.

Like someone else said, the dialogue is repetitive. The Greedo scene already exposited the important parts of the Jabba scene.

But ya know what else? It doesn't. Make. Sense. This is Jabba, not Vader. Jabba is not a hands on kind of guy... thus the entire frickin' reason he hired bounty hunters in the first place! Jabba wouldn't personally go after Han. He'd send lackey after lackey after until one of them hit paydirt. Let someone else do the dirty work, Jabba would never risk his own neck.

And, Crispin's Han Solo trilogy books aside, Han wouldn't stick around on Tatooine if he was trying to avoid Jabba. So Tatooine can't be Jabba's main base of operations or else Han would never have felt safe there. If you're trying to avoid the Mafia, you don't hide in their back yard.

For reasons that have absolutely nothing to do with effects, there's simply no justifying the restored Jabba scene.
