Swift’s six-parter charting her Eras tour began with some riveting revelations – but the drama ebbed away, leaving another piece of mere product for fans

In the behind-the-scenes documentary series Taylor Swift: The End of an Era, the singer Florence Welch ascends to the stage to perform their duet Florida!!! to a crowd of 90,000 people. Welch later reflects on their duet at Wembley Stadium with a mix of awe and bemusement. “Taylor is my friend,” she says. “I know her as this very cosy person, and I came out of that lift and I was like, ‘Oh my God, it’s fucking Taylor Swift.’”

If Swift is a cosy person, The End of an Era – now complete, with its concluding episodes dropping today – is certainly a cosy watch; the sort of lighthearted, low-demand viewing that feels especially welcome in the lazy days leading up to Christmas and stretching towards the new year. Viewers will be familiar with the story. The Eras Tour was great, it tells us. It broke records, burst hearts and boosted the economy. We know she pulled it off. This is only a problem insofar as it means there is almost zero jeopardy in the series, which feels repetitive and thinly stretched over its six hour-long episodes.
