Enjoy
I could never answer any of those favourite band or film questions. When I was younger I could. You get so fervent about things when you're a teen. But, as an adult, I find I can't pin one thing down. I like many things for many different reasons. To be honest, sometimes it's mere fascination that drives my liking rather than being able to pick out specifics like the acting, or lyrics, or story, or innovation. And some things I like simply because they serve no purpose other than to entertain or waste time. They exist just to be enjoyed.
