I think it's worth pointing out that except for Frank Rich in The New York Times, Dreamgirls got the most clueless set of reviews of any major musical for the last 25 years. If you ever want to see how off the mark critics can be, check out those original notices. You'll be shocked.
Rich was the one critic who recognized the innovations in staging, direction, design and performance in Dreamgirls, and how the show was a spiritual cousin to Gypsy, and Jerome Robbins' legendary staging of that landmark musical. Everyone else, almost to a man, blasted Dreamgirls as all style and no substance, and criticized the score as Motown pastiche, with save for a moment or two, it's not.
Rich's unwavering support of Dreamgirls may have backfired when the show lost the 1982 Tony for Best Musical to the interesting, sumptuous, but to me, less satisfying Nine.
Dreamgirls got the last laugh, however, running almost twice as long as Nine.
The 1987 national tour/revival, which played the Ambassador, featured less bells and whistles, and Bennett correctly predicted to the authors that their work would be better received that time around. Of course, nearly every critic did a reversal, finally catching up on what Rich had been saying all along.
