Whatever your politics, it’s hard not to admire the astonishing legal legacy of Supreme Court Justice and liberal trailblazer Ruth Bader Ginsburg, even if you don’t happen to be on board with her current, unexpected incarnation as a pop culture icon. This energetic, entertaining and informative documentary displays her vitality, intelligence, modesty and sense of humor, and packs an even greater emotional punch than the very good recent drama On the Basis of Sex. It’s an unapologetic hagiography, an origin story about a woman who was a nation-changer even before ascending to the top court. (98 min)
