“Maestro,” Bradley Cooper’s biopic about Leonard Bernstein, is streaming on Netflix after a limited theatrical release in December 2023. Like its subject, “Maestro” is many things: a showcase for the acting talents of Mr. Cooper as Bernstein and of Carey Mulligan as his wife, Felicia; an insight into the cultural life of the 1940s to the 1970s; and a meditation on marriage. But at its core, “Maestro” is something far deeper. Mr. Cooper’s film is a devastatingly honest critique of the idea that traditions are disposable and that we as individuals have the power to transcend our own cultural norms to live solely for ourselves.
