I, personally, would go with the unrestored 70mm version. That way, at the very least, we'd get the authentic Six-Track Audio and better source material to base our preservations off of. Besides, there are members like Magnolia Fan who can do the restoration.

Just an observation: The situation Marty McFly describes is very much like the Blade Runner DVDs. The first DVD was 70mm which did retain a film look but has LOTS of dirt, and the other DVDs were restored versions of the 35mm masters... Still, I probably would have gone with 70mm as it would be interesting to see differences in ESB and ROTJ; the grain would be like an old friend.

In any case, I repeat my question: Blade Runner with or without voiceover?
