I hear that the audio for the sandstorm scene is rough, but that Hamill's solemn acting in this scene is more in line with the direction his character has taken since The Empire Strikes Back.
It might be good to use it, if only to replace the grins-all-around exit from Tatooine which exists in the present form of Return of the Jedi.
I haven't actually seen it myself (not touching the Blu Rays) but does anyone who has reckon it's usable or at least salvageable on some level?
