Miller's Crossing: The Series.
This season is like the 8th season of The Sopranos I never got. As a gangster show, this is outstanding.
Best season of the show.
It's all about Gyp. Bobby Cannavale is extraordinary as the villain in season 3 of Boardwalk Empire. Probably the best character the show's come up with.
This season, Nucky is in actual danger. And the last 2 episodes he's literally fighting for his life.
And then there's what happens with Richard Harrow, which I won't spoil, but it's the best stuff in the series.
Buy the first 2 seasons, as well, but get season 3!
