Well, it's not ALL about tourists, but it was certainly a show that was not appealing to a lot of out-of-towners.
I think what ultimately led to the show's demise were it's mixed reviews and it's heavy subject matter. It's not an easy show to digest and understand, and it sure as hell isn't a good old time at the theatre. It's a shame that it didn't last.
