Oh, I think Elton John did a pretty good job at musicalizing BILLY ELLIOT. At least the music feels organic and it doesn't feel like it's there for absolutely no reason. I saw the movie after seeing the show and found myself missing some of the music at points (even if I still think the movie is brilliant in ways that the show quite isn't).
However, with 9 TO 5 it feels like the songs have no reason to be there, and I re-visited the movie after listening to the score and it was so refreshing to see the story told without the distracting, generic, annoying songs.
