There have been a million movies about young women coming of age – and actor-turned-director Greta Gerwig's tale of a Sacramento high school senior (Saoirse Ronan) somehow makes you feel like this is the only one that matters. Her autobiography-inflected story of Christine McPherson – though could you please call her "Lady Bird"? – breathes life into everything from parental arguments to hormone-fueled puppy love to the glories of crushing on bad boys and theater nerd-dom (the awkward school production of Sondheim's Merrily We Roll Along is pitch-perfect). Every performance is spot-on, every detail about being young and stupid in early-aughts Northern California feels right and even the use of Dave Matthews Band's "Crash" works like gangbusters. A triumph, this.
