Don’t get me wrong, I hate JarJar’s voice and essentially every line of his.
But Hal’s edit works much better than some of the more over the top ones, simply because the execution of these grand ideas (like redubbing JarJar, or removing him entirely) is never good enough to work seamlessly. The results of those ambitious edits are interesting, as sorts of animatics or demo reels to give an idea of what might have been. But I don’t ever feel like I’m watching a real film with them. Hal9000’s edits are more modest, as if someone with a brain walked into the editing room during the later stages of piecing the film together. But they work! And, by and large, the result is extremely professional looking and sounding.
