The opening number is one of the best of any musical of the 1990s and "Larger Than Life" is an excellent follow-up.
What kills the show, dead in it's tracks is the "Musketeer Sketch" song. A desperately unfunny comedy number about a comedy sketch.
The score does not regain it's momentum after that, despite the pleasures of "Shut Up and Dance" and the title song (which I captures the spirit of the story better than the song written for the movie version that got recorded by Michael Feinstein and Cleo Laine). It ends act one with a serious song sung by Alan Swann and start the second act with a serious song sung by Alan Swann.
As for Andrea Martin winning the Tony Award, she was up against a girl for "Blood Brothers", a girl for "Tommy" and Laine Kazan for "My Favorite Year". I never saw the show, so I can't tell you why they picked Andrea over Laine.
