Boardwalk Empire Sunday at 9 p.m., HBO
Creator Terence Winters has brought in Jeffrey Wright this season, and he’s excellent. He plays an intellectual Harlem gangster who has contempt for whites and for blacks who are subservient to whites. He has no love for Chalky White, played by Michael K. Williams (above right, with Wright). It’s a complex dynamic at a point when black thinkers of the Harlem Renaissance were considering the way forward, and it’s an excellent way to bring Williams into the show’s forefront. Chalky hasn’t had a good plot since “Boardwalk Empire” premiered in 2010.
Last Tango in Halifax Sunday at 8 p.m., Channel 2
The premise sounds as hackneyed as a Geritol ad: Two widowed 70-somethings reconnecting on Facebook after 60 years. But this six-part series is much more interesting than you might expect. Anne Reid and Derek Jacobi are fresh as the new lovers of a very, very, VERY certain age, and the stories of their adult children and their grandchildren are poignant.
