Jabba the Hutt wasn't a bad addition either, the weakest part was that the Jabba graphics were too fluid and had an ugly muddy gray color (I believe it was revamped in the DVD release).
I don't know, I really hate that scene, to the point where sometimes I skip it when I watch the DVD. I was pretty amazed when I first heard they were placing that scene in the SE, and was impressed when I heard about all the CGI that went into making it. But storywise, I found it to be a really dumb scene once I saw it.
In the scene before you have Greedo saying how Jabba's been looking for him and how righteously pissed at him Jabba is for dumping his freight - foreshadowing two movies ahead that Jabba is a scary badass. When we finally get to see him in the flesh in ROTJ he's as scary as we thought, tossing employees to the Rancor and enslaving Leia.
But in the SE, you have the same scene play out with Greedo (subtly altered, heh heh), and then all of a sudden Jabba finds him. Gee, what does Jabba need bounty hunters for when he can just hang out by the Falcon and wait for Han to show up?
But that's not even the lamest part - then you have the incredibly dumb "tail-stepping" scene. Now, I understand
why they had to do it that way (because of how Han moved around the stand-in actor), but come on. Would the scary badass Jabba of ROTJ let some arrogant smuggler that he's already mad at
step on him? In front of witnesses, no less? Did we really need a scene with Jabba that's played for laughs? Did it add anything at all to the plot?
If you've got a scene that ruins the suspense of a character that you're setting up for film three, plus he's played totally out of character, PLUS it doesn't add anything to the story, then there's a place for that scene: it's called the cutting room floor.
It just struck me as the triumph of special effects over story. For the record, I didn't really have a problem with much else in the SE (Greedo shooting first excepted). But it signaled a trend that I found manifested even moreso in the prequels, this whole idea of "let's do it just because we can".
Lucas needs to print this out and have it stapled to his forehead, so he can see it 24/7:
JUST BECAUSE YOU CAN DO SOMETHING DOESN'T NECESSARILY MAKE IT A GOOD IDEA.
