"Ostensibly a documentary about 85-year-old Supreme Court Justice Ruth Bader Ginsburg, but it feels more like a love letter."
— Peter Rainer, Christian Science Monitor
"Stands as a film that informs, and sometimes even delights with its portrait of one of the more remarkable lawyers, judges, and feminist icons of our time."
— Bilge Ebiri, Village Voice
"The life and work of the associate justice of the US Supreme Court, Ruth Bader Ginsburg (aka "the notorious RBG") is the subject of this dense, inspiring and often playful panegyric."
— Kevin Maher, Times (UK)
"This woman is a force, and the great service this clear-eyed and admiring documentary provides is to emphasize not just Ginsburg's work on the court but how extraordinarily influential she was before she even got there."
— Kenneth Turan, Los Angeles Times
"The documentary makes us grateful for the truth that "It takes all sorts to make a world" - and for the fact that RBG may be staunchest bulwark against the unmaking of that world, in the present American political moment."
— Nigel Andrews, Financial Times
"A celebration of the scrunchie-wearing octogenarian not just as a pop-culture folk hero and millennial meme but as a wife, a warrior, and a true iconoclast, famed for her fierce legal mind and the cutting wit of her dissenting opinions."
— Leah Greenblatt, Entertainment Weekly
