I am 55, I started watching k dramas this year, I am hooked. They are subtitles and I like that because I really have to focus on what's being said and going on in the shows.
A show I really liked was "THE TUNNEL"
"Sweet Home" is really good too.
"Mystic Pop Up Bar" a favorite.
I'm older so everyone and all ages like the same and different shows under this genre. I'm so happy to have found these. My 17 yr old likes Anime. That's how it started with me. My AWESOME Daughter. Enjoy.
