In a year when theatre as a whole seemed reinvigorated by politics and activism, Louisville’s venerable Humana Festival fell distinctly flat, says Michael Phillips. “The case of this year’s Humana Festival, the fifth under the stewardship of Actors Theatre artistic director Marc Masterson, is one of artistic Chapter 11. The festival, a venerable and well-known showcase for new work, needs reorganization, a fresh angle, a renewed reason for being in a theatrical world very different from the one in which it began.”
