You can't look at how full a theatre is as to how much money they are making. It depends on how much someone pays for a ticket. For example, the show has been on TKTS a fair amount recently. There can be a whole area of seats in the orchestra that went on sale at TKTS and is full of people who got them there. The producers wouldn't be making as much money off of those seats as they would off the orchestra seats that are being sold at full price.
Brooks did a bad job with producing this show. He had such a big ego trip that he thought that people would pay 450 for a ticket for this show. At first that price wasn't the premium price that was just general full price. He then realized that no one was buying those tickets because it is 450 for a theatre ticket so he lowered them down to an average price scale.
The show is nothing but one bad joke after another with a forgettable score and lyrics. I got a ticket via lotto and even then wish I had seen something else. I don't see it lasting that long. It is having the same problem that every other show that has played the hilton has had. And that is being profitable in that huge theatre. The only show that ever came close was Ragtime.
