Critics are always going to come to shows like this with a negative bias. Take one of our most respected composers, shovel in most of his most popular songs that were not written to belong in the same show, and tie them together with the slimmest of books.
What you get might be a very decent revue, if the performers are up to it, But critics don't review revues. The last show of this kind was Right Work if You Can Get It. This featured the songs of George Gershwin with a very silly plot starring Kelli O'Hara and Mathew Broderick. This is how Brantley's review began:
Every now and then, a bubble of pure, tickling charm rises from the artificial froth of “Nice Work if You Can Get It,” the pastiche of a 1920s musical featuring songs by George and Ira Gershwin. Most of this show, which opened on Tuesday night at the Imperial Theater, registers as a shiny, dutiful trickle of jokes and dance numbers performed by talented people who don’t entirely connect with the whimsy of a bygone genre.
And this show was a hit, or very nearly. Brantley, as a charter member of the Kelli O'Hara fan club, for which I don't blame him, spends half of the remainder of the review trashing the show and the other half praising Ms. O'Hara.
My own guess was that Roundabout didn't have the money, and/or perhaps the time to put on a major revival on the level of Anything Goes or Twentieth Century, So they chose a relatively inexpensive show that had enough hit songs to at least please if not really connect with its audience.
