I think you don't have to celebrate Christmas to like any version of a Christmas Carol. I've always like the line about Christmas as "a kind, forgiving, charitable, pleasant time: the only time I know of, in the long calendar of the year, when men and women seem by one consent to open their shut-up hearts freely, and to think of people below them as if they really were fellow-passengers to the grave, and not another race of creatures bound on other journeys."
