I don't think this is anymore Disney's fault, then the fault of the general populace this time of year. My DW and I have been noticing a general decrease in the "Christmassy-ness" of the Holiday Season overall the past few years.
I really think there was a "Golden Age" of Christmas, and it has since passed us by. In the movie Christmas Vacation, Clark Griswold watches some old reel-to-reel films about Christmas as a boy. My parents have those same type of videos, and it amazes me to think what Christmas was like back then. The stores had a different air about them, every community was decked out in Holiday glory, there were parades everywhere, and everything seemed to slow down for the entire Holiday Season.
When I was growing up things started becoming even more commercialized. We still had parades, and I remember there was a general "feeling" that you got around the Holidays, and I loved it. I tried my hardest to keep a slow pace, savoring each day around Christmas. But, looking back, it seemed a lot different from those videos of my parents and grandparents, because everything seemed to get more and more rushed.
Now that I'm a father, myself, I get really depressed thinking about how much more that "Holiday" feeling has disappeared. Starting in November people are fighting, arguing, and getting their stress levels up over needing to get this, or needing to get that. There are far fewer parades and community events. Carolers are all but non-existent, and all people seem to want to do is complain. There is far less "community" and maybe that's part of the problem, everyone has isolated themselves within their own little worlds.
I would love to bring back the Golden Age of Christmas, again, but I think society has long moved past it. The best I can do is try to make it wonderful for my own family, by trying my best to slow down the whole Holiday RUSH!
I know this was a long rant (and seemingly OT), but I think things seeming less "Christmassy" at Disney are just a further reflection of how the whole Holiday season is not what it once was. And, that saddens me, no matter what it is you are celebrating during this time of year.
