you guys obviously never saw casablanca in hd, you could clearly read text on signs in the background, see fine detail in faces, etc.
black and white really has nothing to do with clarity and detail
it's all in the film stock/cameras/filters - and of course print source + the amount of remastering
doubtful that silent films will look that much better, but if they utilize the space it'd be nice to have the buster keaton set on two blu ray discs instead of that monster dvd boxed set they released in the past
