A great study of life, connections and death, Mon oncle Antoine (1971) is on my personal short-list of significant films. In it, young adolescent Benoît is an altar boy and general mercantile boy-of-all-work. Set during Christmas week, the young man sees funerals, a kid his own age die, his uncle's drinking problem and his aunt's infidelities. The makings of a great holiday film? You bet; one of the best because it reminds us what's really important in life, even in the midst of decay. Especially in the midst of decay.

Here is an 11 minute excerpt covering the experience of having to pick up the remains of a dead boy on Christmas Eve:
