Helen Shaw has spent the last 12 years as a theatre critic in New York. She says the state of the field is mixed. “As recently as 2007, critic Robert Brustein could say on a panel that we had 35 ‘really fine’ playwrights; even the hardest-to-please observer would say now that the number has more than quadrupled. Some theatre lovers don’t like to categorize the flood because of the canon’s long history of exclusion.”
