I'm happy to say that I have not been fired off a film. The score is usually the last thing to be done. So a lot lands on the scores shoulders. A lot of problems that seem to have nothing to do with the music gets blamed on the music , because it's relatively cheap to change, where as a reshoot etc is not. Music is often expected to help or fix bad cuts, bad acting, bad filming, bad timing, you name it.
