I try to enter directly into the movie's plot and tell the audience something about the story that they can't possibly perceive by just watching the film. For example, if I write for a scene of two people kissing and I write some horrendous music, you know more than just a kiss is happening. I'm always interested in participating that way. Just to write sad music for a sad scene, sure, I'll do it, but it doesn't offer me a great challenge.
