Have to say, having seen the show off-broadway, (Loved it) I am very surprised that the low ticket price is $55. They are going to have a tough time finidng an audience as it is, and this cant help.
The show is also being included as part of the Public Theater's subscription season, so it should have a built-in audience early in the run. Hopefully that will help spread word of mouth if it is as good as some think.
