Well, 70mm is only better if the film was shot on 70mm stock to begin with. Most films are shot on 35 and then blown up to 70 for select theaters.

As far as all the digital cleanup/restoration stuff - it's not a matter of if it's done, it's a matter of to what extent it's done. The '97 SE's started out as just a simple restoration and re-release, and look what happened there. (For the record, I personally don't completely hate the SE's as a whole, just not thrilled with certain specific changes which have been discussed ad infinitum here and elsewhere.)

What we need is literally someone like Ady doing the transfer...someone who is doing it because they WANT to, not because it's just the next item on their workload checklist.
