Taylor is an empathetic portrait of an artist in arrested development, who got famous so young that she spent her twenties and early thirties believing in fairytales. But she’s also a shrewd businesswoman with it.

Less attention is paid to Swift’s music and songwriting craft, which is what happens when a female pop star goes stratospheric. Analysis turns, as it inevitably does in Taylor, to her capacity for reinvention, steely backbone and ability to manipulate her own image.
