Let's start at the very beginning - a very good place to start. When NBC announced they were doing a live, televised version of The Sound of Music, there was a collective gasp of horror. They made it very clear, however, that this was a redo of the stage musical, NOT the film. The stage musical came before the film, they wisely pointed out. There was a further gasp of horror when it was announced that Carrie Underwood had been cast as everyone's favourite nun. Would this become a favourite thing of the fans, or something else?
