Tarnished by a thousand mediocre high-school and community productions, Fiddler on the Roof seemed a lazy choice for BDT, but under Michael J. Duran's direction, this version was revelatory. You remember Tevye, the poor milkman with five daughters who struggles to keep afloat, the guy who sings "If I Were a Rich Man"? And who all too often comes across like a twinkly-eyed Jewish Santa Claus? This Tevye had depth. And so did everyone else in the talented cast. The staging was great and the songs so well sung that you remembered just how brilliant they are. Best of all, this Fiddler managed to be funny and entertaining while still acknowledging the sorrowful historical currents beneath the folktale.
