It is about the triumph of good over evil, family over the forces that tear them apart, a repudiation of greed in favor of the simple things.

Your defense of Die Hard as a Christmas movie is not only credible and possesses merit, but it in itself fills me with the spirit of the season.
Merry Christmas!
