I agree with the Faneditor that "Return of the Jedi" was a letdown in the original trilogy.
First, the video quality is amazing. The edits are smooth. My familiarity with the original movie made me aware of the cuts, but if I had never seen it, I wouldn't have noticed.
The trims to Darth Vader's dialog alone make him far more menacing for longer, which improves the film. Much of the silliness of the Ewoks has been trimmed and they are the better for it.
I definitely recommend this as it utilizes the restored original and not the Special Edition. The ending of the film has been rearranged and I feel it definitely improves the storyline and the feeling of "fulfilment."
