Revenge is a dish served tepid in 'The Visit.' The warmth hobbles this stark musical fable by John Kander, Fred Ebb and Terrence McNally. With this team, the show is certainly worthwhile. But it could really send shivers -- and doesn't. 'The Visit' pulls its punches...The score echoes earlier rhythms and melodies of Kander and Ebb and provides an evocative backdrop. Rivera's husky voice and high-watt charisma go a long way here. And it would have worked even better if director John Doyle's staging was less polite. Scott Pask's skeletal set and Ann Hould-Ward's raggedy clothes scream decay. But the performances don't go there...Wildcat? No. Claire and 'The Visit' are too domesticated for their own good.
