I'm pretty sure the "there's snow, there's a Christmas tree, this is a Christmas movie!" is a joke though. I haven't ever done this joke myself. I guess still need to find what in Die Hard makes it a Christmas movie :) .
it's Christmas eve, part of the premise is a dude returning home t family for Christmas, there's a Christmas miracle (that he survives at all), the villain is after material gain and is about to ruin Christmas, and John's wife's name is fucking Holly! What more do you want‽
I feel like that's a very gradual gradient. Is it only when Christmas is a fundamental part of the story?
For example your comment makes me think of the "Die Hard isn't a Christmas movie" people, but it would have been a completely different movie if not for the office Christmas party.
i think there's a universe out there where Rocky and First Blood establish Stalone as being the contemplative action movie guy. both those movies had interesting things to say about grief, loss, disappointment, and carrying on with the traumas of what pursuit of the american dream actually mean
