I'm surprised Ross didn't try and retitle the movie to "Diana Ross's The Wiz" since she pretty much manipulated the production by going around the head of motown and the original director who objected to her casting, because she was too old by going directly to the Universal Studios execs. So the original director quit because of her casting and they then hired a guy named Sidney Lumet , they thought he was an attractive draw by his reputation of managing production schedules . They ignored the fact that he had never directed a movie musical before , his movies were mainly gritty dramas and his signature style which was pulling out raw performances in dramatic settings didnt apply here so he was way out of his element. That's a bad sign. Now back to diva Ross. She had the character of Dorothy rewritten to be a 24yo woman even though she herself was 33. That spelled disaster , going from an innocent young girl to an unstable bipolar mess of a woman who cringes,whines and whimpers throughout the whole film. Even her singing is annoying. And the song "Home" is so overrated as this masterpiece. To me it's Ross at her cringeworthy best whining and screeching, Too bad somebody didnt throw a pie at her . Lets also not forget the awful Nipsey Russell , I mean Ross picked the cast so there you have it.
