Mastodon has a theme:
#The7FilmsToKnowMe
To which I contributed:
The Princess Bride
Charade
The Big Lebowski
Groundhog Day
Singin’ in the Rain
Blowup
The Big Chill
I chose films which make me feel good to know they exist. I hug myself with glee when I think of them. Other lists of course are possible – favourite musicals, best 21st century, best drama, best romcom, or just numbers 8-14, 15-21 etc – and maybe I’ll do some of those as the mood takes me.
