New York Magazine has kind words for Dodge's production and some of the design, but I'd call it
Mixed overall, since the critic seems to feel the show's writing and concept defeat the production.
http://nymag.com/arts/theater/reviews/62196/ Ragtime has all the stuff Broadway audiences should eat up: A plot that hinges on murder, vengeance and injustice; a story whose moral seriousness glows like polished veneer; a number of fantastic voices onstage; the requisite number of “My dreams have died” songs. It’s an ambitious sprawl of a story, adapted from E.L. Doctorow’s 1975 historical pastiche about the early, heady days of the twentieth century. And in this revival—the show first appeared in 1998—director and choreographer Marcia Milgrom Dodge and her 40-strong ensemble cast do their damnedest to keep things moving forward with the zeal and energy of a well-tuned engine.
So why does the whole shebang come off like the product of a too-efficient assembly line? Neither Terrence McNally’s mishmash of a book nor the sometimes-syrupy songs (by Stephen Flaherty and Lynn Ahrens) do the show any favors. And then there are the inherent problems of Doctorow’s novel, a puffed-out chest of a book that uses its characters as flattened symbols of racism, intolerance, hypocrisy, and disillusionment. It groans under its own lesson plan, and the musical follows suit.
Begin at the beginning and go on till you come to the end: then stop.
