this comes down to money spent.
the 2004 release had every single frame digitally scanned by lowry who then sharpened it up further.
now, if you take the original 93 version of the film and digitally scanned it, then it would be nice and sharp, just like the 2004 release, however, I've heard nothing thus far that says this has happened. merely that a 93 print has recently been rewashed. my take on quality really plays off how the 93 print is being transfered into a dvd master. if it's by digital scanning, then it should be quite nice, maybe not up to lowry standards but still good. if it's done in the more normal way, then obviously, it will not be.
