This edition of Downton Abbey is kinda-sorta a merger of two other well-known movies; The Great Gatsby and Singing in the Rain. WHAT? OK, the opulence of the 1920s in the South of France Riviera is one half of the story line, with the plot line from Singing in the Rain openly stolen in broad daylight for the back-at-home sequences for the other half. And Maggie Smith steals every scene, even the last one.
