Edward Scissorhands.
Christmas film?

Edward Scissorhands is told on a snowy night, and its best-known image is snow falling over a Christmas party. It feels wintry from the first frame.

Most of the film, though, takes place in a pastel suburb that rarely looks like winter. Christmas arrives late, as the setting for the climax rather than the subject of the story. On the rubric that means low setting saturation and a real case for Winter rather than Christmas.

It is a Halloween film for a lot of people too: UK searches for it peak in October, not December. That makes it a good test of the difference between the ruling and Festive Factor. Decide whether the snow is doing the work that Christmas is getting the credit for.
