I do love science fiction but it's not really a genre unto itself it always seems to merge with another genre. With the few movies I've done I've ended up playing with genre in some way or another so any genre that's made to mix with others is like candy to me. It allows you to use big mythic situations to talk about ordinary things.
I worked on scores. I went to the musical library in Berlin which is very famous. I discovered that we had scores of Beethoven printed scores of Beethoven that are full of mistakes. Not the wrong or false notes but the wrong dynamic understandable things.
