Screenwriter Diablo Cody and director Jason Reitman (their third collaboration, following Juno and Young Adult) revisit Mary Poppins by way of bleary-eyed Middle America, substituting the idea that life gets better – or love means sacrifice – for a childish fantasy involving the healing powers of a 20-something, Greta Gerwig-type free spirit.
She’s a sort-of hipster Mary Poppins in a crop-top.
Davis has to be Tully’s version of Mary Poppins, an nearly magical entity that attempts to fix the family she’s caring for.
On the surface, this is a cross between Mary Poppins and The Hand That Rocks the Cradle, so from the very start there's a sense that there's something wrong about Tully.
Tully is Mary Poppins for the modern age, an unflinchingly realistic examination on the struggles of being a mother, and what giving a life can do to yourself, both physically and mentally.
