If you liked the movie "the Imitation Game' - check out The Bletchly Circle - same WWII timeline.
Also, same era, would recommend another British who-done-it drama series called Foyles War. Both are on Netflix.
Not sure if anyone mentioned Mad Men.
Penny Dreadfull was, uh, different, - unfortunately they seemed to quickly end the series in year 3.
Dexter. Ray Donovan.
Power (Starz), just about done with season 3. (Like Peaky Blinders fast-forwarded to 2016 NYC setting?).
