Imagine you'd just spent millions of dollars creating cutting-edge special effects technology, and millions more to market a re-release of a beloved movie. And then you stumble into a review meeting, and the image that confronts you on the giant, costly movie screen is this:

This really happened! I know it's been a dozen years, and that this image was made a little less shitty when Service Pack 2 for Star Wars came out with the release of the DVD. But still — imagine that meeting, and coming out of it with the boss saying "Yep. That's good enough."
I always figured that Jabba looked so different (crappy) because he was supposedly a few years younger... what I thought was worse was the whole Greedo shoots first thing—and put aside the whole Han's the type of guy who would've shot first argument—the idea that Greedo is sitting across from Han—like 3 feet from him tops—and still can't hit him, not even wing him!, with his gun—preposterous!
