One year after taking one final bow on The Eras Tour stage, Taylor Swift is pulling the curtain back. The End of an Era, a six-part docuseries focused on the biggest tour yet of the superstar’s career, premiered Dec. 12 on Disney+, with all six episodes now streaming.

And while The End of an Era could have existed as pure fan service — and that is certainly an aspect of the opening episodes, with slow-motion shots of an unstoppable Swift and adoring supporters — the heart of the series is a documentation of singular pop spectacle, unpacking the personalities behind the tour and how they came together to produce something so massive.

Of course, that starts with Swift, whose attention to detail is both unsurprising and mesmerizing to witness in the context of pushing the Eras shows to become more dazzling. The docuseries showcases the germination of the tour, and how it kept changing — including the incorporation of a new era, The Tortured Poets Department, as well as recurring and guest stage presences.

Her passion to entertain, to take care of her tour family, to clarify her artistic intent and to also simply enjoy every moment of the tour is presented as a balancing act that she can’t help but keep up. Just as there were no half-measures in the three-hour-plus concert, Swift does not hold back in The End of an Era, and viewers finish each episode with a greater understanding of her intent.

The Eras Tour will forever be a special experience for countless attendees, and The End of an Era honors that indispensability — while also tossing out new tidbits that even the superfans will appreciate. Here are 22 things we learned from The End of an Era.
