From Variety:
“Highly personal and original, “Martha & Ethel” deals with a subject rarely seen onscreen before: nannies and their long-lasting influence on the children they raise. Criss-crossing the paths of the filmmakers’ own nannies, a German-Catholic and a Southern black woman, this remarkable docu provides a piercing yet subtle look at the inner workings of two families as they change over five decades of American history and politics.”
