Whether old or new, it is a hot mess of the highest caliber - a dazzling and dizzying documentary mixed with star turns, syncopated rhythms, stylish attire, fierce tap-dancing and weak subplots...For nearly three hours, 'Shuffle Along' throws at its audience nonstop sound and fury and historical detail. It's like climbing aboard a rocket that doesn't stop spinning...But the storytelling is chaotic and choppy, and the characters are painted in broad strokes. The second act, set after the show has become an overnight sensation, comes off as superfluous...McDonald plays it up as an over-the-top diva, while Stokes once again proves himself to be an outstanding leading man...It should come as no surprise that something so experimental and ambitious needs more development.
