Taylor Swift released a Disney+ docuseries "The End of an Era" and a concert film "The Final Show" that chronicle her record-breaking Eras Tour and include a moment in which she tells her dancers the tour drew more than ten million concertgoers.The series intercuts intimate backstage footage with appearances by Travis Kelce and Ed Sheeran, highlights a new album, "The Life of a Showgirl," and recounts darker episodes including a terror plot in Vienna and a fatal incident in Southport.Critics have faulted the docuseries for a disjointed structure and questionable timing even as it underlines the tour's global scale and commercial impact.
