As KMcG said, Supernatural. Yes.
BBC's Sherlock maybe?
Game of Thrones, Prison Break, Revenge, Hannibal, Heroes, The Walking Dead, Dexter
Also I know this is an Anime not TV show but have you ever seen Death Note (the anime series not film) because it is amazing oh my god
I love Pretty Little Liars and American Horror Story and I also recommend:
Supernatural
Sherlock
Doctor Who
Hannibal
Teen Wolf
Glee
Are you looking for current series, or is it okay to list some that have ended? This is a mixture of both:
Alias
Fringe
Heroes
The Tomorrow People
Being Human (UK version)
Supernatural

Haven
Bates Motel
Luther
Misfits
Sherlock
Prison Break
Revenge
Harper's Island

Person of Interest
Supernatural, warehouse 13, and Fringe watching those now on Netflix
Try watching revolution, the walking dead, breaking bad, arrow, game of thrones and i think sex and the city?

Basically just anything like those. I'm not really into comedies, though.
