Honestly, she found the escape hatch with Folklore/Evermore—character songs, fictional writing, world building. And even her best pre-folklore stuff like 1989 and Red existed in a heightened reality—a kind of expanded technicolor semi-autobiographical state. The best songs on Lover (Cruel Summer, The Archer) are less about specific Taylor-shaped experiences.
I think the big cul-de-sac Swift is stuck in is the grievance-based persona. What works for a skinny supposedly dorky eternally teenaged character really doesn’t fly for a billionaire who is one of the most famous humans on earth who spent a full year on a world-stomping victory lap.
Her persona is at odds with the work/text. And the work/text is lazy. Our girl styles herself as “the English teacher” but she clearly hasn’t read a book since the 12th grade. Which is fine, she’s rich and famous. But she’s not growing as an artist AND she desperately wants to be loved for giving minimal effort. She should probably take a couple years off and come back with some new tricks. A lot of artists without a process and without a great ability to make something out of nothing run out of steam in their mid-thirties.
