Despite the mostly awful reviews, Disney has got enough qoutes to put out a heck of a spectacular ad in the Times, to adorn the sides of buses, and to plant outside the theatre. Even the bad reviews praised the spectacle of it, which is all some people need to hear. I think a lot of people sort of assume that the critics are "out to get" Disney, and don't take seriously their pans. It'll run for at least 3 years, maybe longer. And the TV ad campaign will be designed to make children crazy to see it.
That said, Disney had better start developing some better shows than Tarzan, or they're going to tarnish their reputation. I think alot of people are going to see Tarzan, be bored stiff by it, and think twice before they see another Disney musical.
Behind the fake tinsel of Broadway is real tinsel.
