It would have satisfied even the most voracious history buffs if Rory Kennedy, youngest child of Robert and Ethel Kennedy, had enlisted her mother's perspective simply as a fresh angle on the Kennedy years. But this movie is so much more. Intimate, humorous conversations and never-before-seen images from the family troves uncover an enthralling story of a vivacious, authentic heroine whose transformation - from rambunctious Republican firecracker to savvy Democratic campaigner to socially conscious single mother of 11 - arcs definitively as her husband's drama unfolds.
