‘Two Trains Running’ at Goodman: As tumult besets their world, diner denizens grasp at life

Review: We need a new word to describe the quality that makes every August Wilson play a red-letter event of any theater season. This single new descriptor would meld the two features that Wilson always mixes with such ineffable ease: charm and poignancy. They are the stuff of “Two Trains Running” at the Goodman Theatre, a beguiling portrait of the human condition as an uphill battle – and the difference a leap of faith can make. ★★★★★
