My favourite genre lies inside myself, and as I follow my favourite stories, characters and images, it sums up to a certain genre. So at times even I have to try to guess which genre a film will be after I've made it.
When you just get fantasy stories that are about fairies or goblins, I just don't care. I'm never going to meet a goblin, it doesn't mean anything to me. So my definition of fantasy is very broad, it's anything to do with memory, or dreams, or ways of interpreting or making sense of the world.
