Sydney is rather like an arrogant lover. When it rains it can deny you its love and you can find it hard to relate to. It's not a place that's built to be rainy or cold. But when the sun comes out, it bats its eyelids, it's glamorous, beautiful, attractive, smart, and it's very hard to get away from its magnetic pull.
If you wanted to show a mirror to people that says, 'You've been drunk on money,' they're not going to want to see it. But if you reflected that mirror on another time they'd be willing to. People will need an explanation of where we are and where we've been, and 'The Great Gatsby' can provide that explanation.
