“Scarlet Pimpernel”

Fop by day, dashing hero by night, Sir Percy is the central character in “The Scarlet Pimpernel,” a swashbuckling musical comedy set during the French Revolution. That’s right. Swashbuckling. Musical. Comedy. Of the three elements, the comedy works best in this play, where the generic music does little to set the tone. The production–which opened Wednesday night at the Shubert Theatre–comes courtesy of Frank Wildhorn, whose other weird musicals include “Jekyll & Hyde” and “Civil War.” His musicals have a strong pop edge that don’t fit the period pieces he’s trying to create.
