The jarring first scene of Lady Bird grabs your attention and quickly alleviates any fears of the movie being a run-of-the-mill high-school drama. Written and directed by the indie-rific Greta Gerwig, the film is a snapshot of the final two months of the life of Christine "Lady Bird" Macpherson (Saoirse Ronan) as a 17-year-old. The camera follows her as she applies to college, has a tense and testy relationship with her mother Marion Macpherson (Laurie Metcalf), tries to be cool in Catholic school, loses her virginity, dates boys who are awkward or pretentious or both, and so on.
