In his new film, which premieres this Sunday night on PBS, documentarian Ken Burns examines the tangled lives of Theodore, Franklin, and Eleanor Roosevelt. "It was not our intention to make a puff piece," Ken Burns told Senior Editor Damon Root in an interview this week, "but a complicated, intertwined, integrated narrative about one hell of an American family." Root reports that Burns was just partially successful. At its best, Root writes, The Roosevelts: An Intimate History offers a warts and all portrait of the family. But at its worst, the film ignores historical details and underplays the family's abuse of political power.
