The docs give some good examples of one use of Directive: to avoid 
nested graphics directives.  Thus the example
   Plot[{Sin[x],Cos[x]},{x,0,10},
      PlotStyle->{Directive[Red,Dashed],Directive[Blue,Thick]}]
from the "home page" of Directive, although wordier, is to my eye 
easier to read than the equivalent:
   Plot[{Sin[x],Cos[x]},{x,0,10},
      PlotStyle->{{Red,Dashed},{Blue,Thick}}]
The longer and more numerous the directives are for the various elements 
of a plot or graphic, the more useful Directive becomes in untangling 
the syntax for the eye.
