Actually, they did revise the show two or three years before shutting it permanently. They closed it for a good while, retooled and altered the show scenes and script,changed the martial arts type, and redid the stage/effects which were in disrepair. The new show was a mild improvement, and the script was less corny ( a good thing)....but it just never caught on with the public. Perhaps the Sindbad theme was just not the GP's cup of tea.
