True Detective if you haven't seen it.
Tyrant on Fx is very solid. About an middle eastern ex-pat that gets sucked back into Arab politics after 20 years in America when his father dies, and leaves his crazy brother and, by proxy himself control of small country.
Power, the 50 cent show, is surprisingly decent (7/10). It's like a ghetto Sopranos, about a drug dealer who sort of wants to go straight, but still has to deal with his crew and various other drug cartels. Some of the writing is horrible, but overall, it's enjoyable.
