Damien Chazelle likes protagonists who have one defining goal. They are driven and they are ready to sacrifice in order to achieve their goals. Their ambitions are jealous gods and don’t allow for any other gods beside them. Relationships? Happiness? Love? These take a backseat. Chazelle’s characters’ pursuit of excellence requires them to be singleminded. You don’t get there by being good at many things, you get there by being excellent at the one thing that gets you there. And there’s a price to singlemindedness.
Looking at it differently, you could also say this: Damien Chazelle’s protagonists are frightened, of their feelings and responsibilities – and if you want to run away, what better destination than the moon?
