Second favourite would probably be Ingmar Bergman’s Fanny & Alexander (1978), which, if I actually had time, would watch again, but alas, as things go each holiday season, there’s less time to appreciate a 5 hour mini-series, let alone multiple TV specials.
The nature of TV holiday specials is to hit all the sentimental marks so you, the audience, click off the idiot box feeling warm & fuzzy inside; a sense of goodness about humanity; anticipation of your own family gathering; seeing predictable dramas unfold and issues resolved so you too can handle your idiot brother, egotistical sister, detail-oriented mother, and yapping father before a single slice of turkey is cut.
Seasonal films are in some way coping mechanisms, because they reassure adults that no matter how annoying family will be, nor the gigantic mess leftover from guests, nor the segment of visiting relatives you’d like to accidentally forget to pick-up from airport, nor the lecturing you’ll get from an elder or big mouth, You Will Prevail. You will remain your own Special Person. And when New Year’s chimes in, you’ll be satisfied you fulfilled your familial obligations, and are fully entitled to pickling your brain in sparkling wine.
