I watched the first film so far and wow! These preservations are great! The color and detail, pre DVNR, is astonishing.
It seems to my eye that much of the laser fire throughout the first film is brighter than in other video versions. Could this be due to the fact that it was transfered so long ago and that the source print would have had less fading?
I also actually don't mind the bits of dirt on the film. It's a subtle reminder to me of the beauty of motion picture film, the way it was used for 100 years before all of the new age digital cameras.
