Rodgers & Hammerstein's Cinderella was in the Broadway which turned out to be the wrong theater commercially. The capacity of the theater was simply too big, and thus supply exceeded demand. Cinderella was selling an enormous quantity of tickets per week, as many as almost any show on Broadway, but its percentage of seats sold generally hovered in the 60-70% range. If the show had been in a 1100 seat house instead of a 1600 seat house, demand would have been very high, which would have meant more premium tickets sold and less seats sold at discounted prices. Many people have described the Broadway and other huge capacity theaters as places where good shows go to die. (Mega hits like The Lion King and Wicked are a completely different story.)
In terms of the artistic presentation, there was nothing wrong with the show at the Broadway, so this is only an economic analysis.
