When Edmond Rostand’s Cyrano de Bergerac opened in 1897, it was hailed not only for its poetry but for its elaborate sets—one for each of the five acts, from bakery to battlefield—and for its poetry and grandiose passions. Martin Crimp’s version of the story of unrequited love, produced and directed by Jamie Lloyd at BAM, has only the faintest glimmers of any exaltation. More often it’s simply disappointing.
