A fascinating window into the era of Prohibition. Set in Atlantic City, "Boardwalk" traces the evolution of Nucky Thompson from a merely corrupt official into a full-fledged gangster. Although one might expect this premise to result in a show heavily tipped towards a male perspective, Nucky fully meets his match in the character of Margaret Schroeder. Both characters are brilliantly written and acted, as are the constellation of secondary characters, whether fictional or real (e.g., Al Capone and Lucky Luciano).
While the era of gangsters has been exhaustively explored in film and TV, the constitutional amendment prohibiting alcohol that made it all possible has been largely ignored. Too bad, given the parallels to our current "war on drugs".
Oh, and the costumes alone are worth your time.
