The Light Opera Works production of Rodgers and Hammerstein's classic has a fine orchestra and lavish sets, and the harmonies are sublime, especially when the nuns sing. But none of this compensates for the paper-thin characters offered by the cast, with the exception of Jamie Axtell as the talent scout/unapologetic mooch Max and, sometimes, Winifred Faix Brown as Mother Abbess. Katrina Kuntz plays Maria as if she were a young Kathie Lee Gifford, and though Larry Adams as Captain von Trapp could melt stone when he sings "Edelweiss," most of the time he's simply wooden.
