Last week, in my review of the marvelous family drama Wonder, one of my few gripes concerned the implausible drama-club scenes, and I wrote, “Movies never seem to get school theatre right.” Clearly, bitching occasionally pays off. Because less than a week later, I watched writer/director Greta Gerwig's Lady Bird get school theatre exactly right – which wasn't shocking, in retrospect, considering this coming-of-age comedy appeared to get everything right about damn near everything.
