It’s totally a Christmas movie. It’s a Christmas movie for people that can’t stand the saccharine pap that passes for Christmas entertainment. That’s how a friend of mine introduced me to it. It was coming on Christmas time and I was complaining how awful the entertainment of the world gets this time of year, with Burl Ives crap fests, and the teary BS. And he said “watch Die Hard”. Great advice. There actually is a pro-family message in the movie. And it’s probably the most technically perfect action movie ever.
It’s no more cultural rot than all the other Christmas movies. Actually it’s much less. Because 90% of the “traditional” Christmas movie Die Hard is actually a good movie.
I don’t really care for the traditional Christmas movies either, I find them rather boring. I’m not a devout Christian either, but the entire American Christmas experience disgusts me more each passing year with all the hypocrisy.
