Love Downton Abbey?
Try The Forsyte Saga. Featuring Homeland's own Sgt. Nicholas Brody (a.k.a. British actor Damian Lewis), this show about a stuffy English family through the generations has all the period-piece drama of Downton, presented in a far more engrossing, realistic manner. Don't be thrown off by the massive time jumps in the first few episodes — once this show falls into place, it's unbelievably hard to turn off.
