Also most families only have 1 or 2 important Christmas traditions, there's just such a wide variety of them that for movies to "appeal" to a wider audience they have to do a bunch of stuff to hopefully hit upon a tradition that matters to as much of the audience as possible.

I never thought about that last part, but it's so true. Movies try to check of every single holiday box, but most of us only do a few of those things. Like, I can't remember the last time I went to a tree lighting. Maybe as a kid. But every Hallmark movie features the whole community in Town Square gathered for it like every single town stops what they're doing to all just gather around a tree across the world.

In other countries, Japan for example, gift giving is almost automated in their society to the point of being able to pick up simple gifts nearly anywhere, fancy fruit or what have you. When you get the easy gifts out of the way you can focus on those 1-4 people that are significant to you. But that wouldn't work in the West, gotta buy all the expensive stuff to take that red into black.
