If you are selling tickets, people are going to ask you what you think. Considering it's anecdotal, I really can't judge- but if someone is deciding between a few shows, they're going to ask the seller's opinion on their choices.
But audiences DONT necessarily prefer shows packaged like Rocky. Which is why it's closing. And why Bullets is closing. And why any number of musical adaptation of an existing property fail.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
