But Swift already has been murdering her former selves in a series of albums in which she keeps reinventing herself: country-lite star, pop-rocker, and most recently an EDM and hip-hop dabbler. All those iterations were on display in a seamlessly professional presentation that never really strayed beyond its tightly scripted boundaries. Even the singer’s two monologues felt a bit canned, and the show hummed with remote efficiency. Long gone is the awkward teen with the guitar pouring out her diary entries about high school crushes and nerdy shyness. In their place has come a more assured performer who takes cold, deadly aim at anyone who might do her wrong.
