I can think of a lot of tv type serials that don’t drop swear words. Older ones.
Movies, again anything old.
FWIW, most of the stuff we watch is old.
Without knowing a genre or genres you prefer, if any, go for age.
Yup, the “go for age” - come on, you can have a serial that doesn’t use bad language.
we were watching “The rookie” - nice season 1 and 2 and it didn’t have bad language.
