WICKED

Can someone please explain to me why WICKED continues to gross over $1 million dollars a week? David Stone has done something right. And it can't just be the show itself - there are tons of great shows that closed because they couldn't sell enough tickets. There are tons of great shows that are still running, but making MUCH less money. And - from what I've heard - WICKED is a good show, but not a great one. So what is it?

I want to know what it took. What did he do to make it work?
