'WE SPEAK DANCE’ on Netflix (Jan. 1) This new dance-and-travel series, to be unveiled on Netflix on New Year’s Day, explores the world through movement. Hosted by the dancer Vandana Hart, the program investigates traditional and urban dance traditions on a global level. So far, there are five episodes with locations in Paris, Vietnam, Beirut, Lagos and Bali. “It’s going to be a real mixture of different styles,” Ms. Hart says in the trailer. And it’s a good excuse for a New Year’s resolution: In 2018, see more dance.
