A few things here. . .
1. I've seen a good many of them. Some on that list aren't really Christmas movies. (Maniac Cop 2? Lethal Weapon? Die Hard? Being set during Christmas does not make them Christmas movies). And some are so old that they're only going to appeal to me as a historical curiosity.
2. Nearly all of the made-for-TV and DTV Christmas movies are fucking terrible. Networks like The Hallmark Channel and ABC Family churn dozens of them every year, but here's the kicker: They are not good! I have tried to watch them and they are almost all shitty love stories that usually go something like this: Lonely divorced mom gets a magical Christmas present in the form of a man to love her. Which leads me to my next point. . .
3. The thread title is "There should be more GREAT Christmas movies." Emphasis on the great. Can you name even FIVE great Christmas movies from past decade? Or hell, even five really good ones? I thought A Christmas Carol (2009) and Four Christmases (2008) were pretty good, but that's it. That's all I got. You?
Like I said, I don't consider a lot of what's on that list to be legitimate Christmas movies. Tangerine is certainly not. Horror films, even if they're Christmas themed, are not what I mean when I say "Christmas movies." And then you have shit like Nativity 3: Dude, Where's My Donkey, and I hope it's obvious why I'm choosing to ignore its existence.
If anything, the list you posted just proves my point: Not much at all has come out in the past several years in terms of quality Christmas entertainment.
