The ones that I am following right now are:
Banshee - Cinemax
True Detective - HBO
Shameless - Showtime
From Dusk Til Dawn (The Series) - Netflix Canada
House of Cards - Netflix
Vice - HBO
I watched the first three. They are really awesome. Banshee is one of my favourite TV series. It affected to my actions in tough time.
Anyway, I want to mention Dexter (Showtime), Black Mirror (it was added to Netflix), White Collar (USA Network) and Fargo (Amazon, especially the 1 season).
