"Maestro" is a superficially engaging soap opera about a famous marriage going off the rails thanks to a famous musician's promiscuous bisexuality. That the musician happens to be Leonard Bernstein, the most charismatic figure in American classical music in the second half of the twentieth century, gives the film a certain allure, enlivened by the virtuoso performances of Bradley Cooper (also the director) as the maestro and Casey Mulligan as his sparkling, long-suffering wife, Felicia. Like all Hollywood biopics of such figures, the film is more interested in the great man's personal foibles than what made him so celebrated - i.e. his musical genius. The film, shot partly in black-and-white (the heady, glamorous early years) and hyper color (the troubled later years), skates through the prodigious career with an occasional cinematic flourish, a great deal of incomprehensible, overlapping dialogue and little regard for what propelled it besides the hero's manic energy. (No one seems to mind his chain smoking amid irrepressible hugging and kissing.) The film's climax is double-barreled: an uncomfortably invasive account of Felicia's fatal struggle with cancer and a protracted segment showing the maestro outdoing himself in podium theatrics while conducting Mahler in a vast English cathedral, apparently so transporting that Felicia is able (once again) to overlook the less appealing side of their union. If the filmmaking becomes tiresomely overwrought, while evading true insight, well then so did its subject.
