Do not alter the film or its aesthetic. Just restore it.

Removing grain and fixing matte lines is altering the aesthetic of the film and fixing matte lines is altering both the aesthetic and content of the film. Dirt and scratches are instances of foreign objects attaching themselves to the film and damage to the film, and therefore should be removed.

The three original audio soundtracks of 1977 should be included, as they are all equally unique and as much a part of the film as it's original image is.

That's all I would want. No DNR, no updates of the special effects, no new mixes, no nothing. Just a classical restoration.

Exactly. This. This is it.

This should be our mission statement.

I've never seen it stated better.
