With a Tony in its knapsack, the biggest budget in town, and a faithful core audience, the Alliance Theatre certainly has huge advantages over all theaters in the city. But such achievements can also be heavy burdens. It would be easy for the theater to sit on its laurels and deliver the same repertoire each season, but that's not what Atlanta gets from the Alliance. Artistic Director Susan V. Booth provides polish and daring in equal measure. The Alliance's Kendeda Graduate Playwright Competition cultivates young playwrights while smart productions like this year's Good People keep the audiences in the seats.
