You should expect to apply some unsharp masking in PS, as any CCD scanner
will produce a softened scan due to aliasing (unless the scanner/software
applies some itself). However it's not clear if this is the extent of your
problem. Are scans soft across the frame, or some parts of the image are
softer than others?

Grain aliasing! Best suggestion is try a range of films until you find
emulsions which don't cause this artifact. Or, er, defocus the scanner
slightly ;)
