35 mm film was still superior in resolution to HD if we convert everything to "lines" rather than pixels. (HD is about 2 X10^6 pixels while a 35 mm film is 12X10^6).
70 mm film even moreso.
HD "seems" high res because of its "black space" which enhances the contrast between matrix and the scan lines.
Since film is pretty much a dead medium except for some trick photography and for some "tinted style" documentaries, your pleas will fall on deaf ears I think.
I dont think that film schools even use "film" at all.
I think digital cartoons are far superior to film, mostly because of the depth of field with many more "layers" allowing for interaction among the depth of field.
Even walt Disneys later film cartoons couldnt compare to the quality of the scenes that Digital animation allowed. Think about the movie "UP" , there hasnt been a film cartoon as visually perfect as this one.
