In the classic Bill Murray comedy Groundhog Day, a caddish weatherman is trapped in a small Pennsylvania town in midwinter. He is forced to relive the same events over and over until (as the trailer says) "he finally gets it right." A similar redemption came last night for the Metropolitan Opera's first Don Giovanni this season, presented in a 2012 staging by Michael Grandage. This was the fifty-first performance of this well-worn show. Last night, it finally roared to comic life. The spark: four strong debuts, three on stage and one in the orchestra pit.
