Aside from the obvious big ones like Home Alone/Love Actually/The Holiday/The Grinch etc.
It's just for me so it doesn't have to be kid friendly, though I don't like really scary stuff and I'd like an overall upbeat vibe to it. Nothing too cheesy and 'Hallmark' though! I enjoyed 'Christmas Eve', the characters all stuck in New York elevators on Christmas Eve, and 'The Nativity Story', about Mary and Joseph as they head to Bethlehem with Herod kicking off in the background.
Can you think of any more I might enjoy please? Bonus points if it's free with Prime or on Youtube as I no longer have Netflix.
