"This is the subjective line between homage and rip-off. The old joke is that homage is when you copy someone else; a rip-off is when someone else copies you. But to me, it’s about the difference between drawing inspiration to create something new, versus slavishly copying to create something derivative. That’s the difference between great artists stealing and bad artists copying.
