Critics accused Chekhov of lacking skill; they naturally did not see anything funny about the distressing plays that Chekhov called comedies. But what happened to Three Sisters was even worse. Regardless of Chekhov’s genuine comic intentions, the opinion that Three Sisters was written as a drama still exists in criticism. In its first edition, Three Sisters was subtitled as “drama”; the fact that Chekhov insisted that he created comedy, even vaudeville (which he seriously argued about with Stanislavsky and Nemirovich-Danchenko), sank into oblivion.
