Don't nearly all Christmas movies suck?

The relative merit of a movie can be measured by the dubious yardstick of what it adds to culture, be it pop culture idioms or the imagery within the movie:

For example, a Christmas Story:

Idiom: "You'll shoot your eye out!"
Idiom: "I can't put my arms down!"
Idiom: "It's a major award!"
Imagery: the leg lamp.
Imagery: sticking your tongue to a flag pole.

And a Christmas Carol(various versions as well as the original literary work):

Idiom: "God bless us, every one!"
Idiom: "Bah! Humbug!"
Imagery: The three ghosts of past, present, and future.

It's a Wonderful Life:

Idiom: "Every time a bell rings, an angel gets its wings."

The folks who make/made movies with cultural merit on a regular basis (Lucas, Disney, Pixar, Mike Meyers, Jim Carey), have it down to a veritable science. They typically have many imitators, which almost always wind up being fluff and garbage, and usually, movies with cultural merit are accidental and often the equivalent of cultural one hit wonders. ("They're coming to get you, Barbara", "Hello, my name is Inigo Montoya...", "What is your name? What is your quest? What is your favourite colour?", "Open the pod bay doors, Hal")

But then again, what do I know?

Jeez John. You put alot more thought into it than I did. I saw the trailer, thought to myself "boy this is going to suck", and went on ;-)
