I'm surprised this lasted as long as it did. It was in the wrong location, and I don't mean the particular theater, I mean on Broadway itself. It was more of a stunt show or a movie theme park ride. Vegas, Universal Studios, Orlando ... they have places for these kinds of shows and Broadway still isn't one of them.
I know many people think Broadway itself has turned into the northeast version of a theme park, with 'Phantom', 'Chicago' and 'The Lion King' being the favorite rides for returning tourists, but it's not there yet. 'King Kong' was never going to last on Broadway.
