“Theater is a social and collaborative art form, and a playwright’s work is no doubt most fully realized on the stage. But to encounter plays on paper is to encounter them in their platonic form. You’re glued to the playwright’s words, not sitting in Row K jostling for an armrest... While reading, you can submit more perfectly to the author’s spell and, what’s more, you are your own casting director.”
-- Dwight Garner, “Submitting to a Play’s Spell, Without the Stage”
