Its sort of a teen show but Dance Academy. I feel like its one of the few teen shows I've watched where they seemed to plan it from the beginning and none of the storylines are OTT/ridiculous. There's also a movie too! The episodes are short (20 minutes) so it makes for easy watching.
Unbreakable Kimmy Schmidt has been fun to watch with my teen daughter, it was a brilliant one to move onto after getting through all of Friends (twice) in the pre-teen years, she also loved The Good Place.
I enjoy all of the gritty crime ones. I see Happy Valley is on there, my Mum loves it but I've tried and tried and can't get into it.
Cannot wait for Line of Duty, there look to be some good TV series coming up that also aren't on Netflix.
