Propelled by a pair of knockout performances from Jennifer Hudson and Cynthia Erivo, both making their Broadway debuts, this transfer from London's Menier Chocolate Factory takes a minimalist visual approach to a story that sprawls across decades and continents, training the focus firmly on the twists and turns of Alice Walker's highly populated, Brontë-worthy tale...Marsha Norman's book cunningly trims the story to essentials, and the songs by Brenda Russell, Allee Willis and Stephen Bray get the job done...What sets the production so strikingly apart from the original is director John Doyle's spartan approach to the physical setting, which he also designed...I'm not always a fan of Doyle's approach but here...he shows a mastery of character revealed. And so in the best show-biz sense, The Color Purple is more than the sum of its considerable parts. It's a fine old-fashioned celebration of endurance, grace and goodness, given a powerful African-American depth.
