The country crossover whirling dervish who has overtaken much of modern pop cultural consciousness appears to stop all space and time for an epic concert film that feels like an interplanetary transmission of what it feels like to come of age while expressing highs and lows through multi-genre sonic storytelling. Sam Wrench’s concert documentary Taylor Swift: The Eras Tour (A-), filmed during the L.A. leg of her landmark U.S. tour, largely captures this sensation in action with a smorgasbord of mini-sets from the artist’s albums spanning nearly two decades; and Swift’s singing, dancing, emoting, comic asides and fan-servicing are dynamite in close-up. A Zapruder film examination of millions of cameraphone TikToks and Insta posts seen over a past year culminates in a widescreen masterclass in heavy-duty camera work and sound mixing to capture the live experience and artist/fan interaction in an urgent way. You may think you’ve seen all of this already,  but it’s hardly been rendered before in any way like this supersized format. After a bit of a slow open with pleasant singles from the “Lover” album, the film gains momentum with the hit songs of “Fearless,” the crafty tunes from mellow pandemic record “Evermore” and fierce bursts from hard-slapping “Reputation.” The concert repeats a cycle of more typical concert fare with mainstream songs from albums “Speak Now,” “Red,” and ultimately “1989” interlaced with indie deep cuts from the more experimental “Folklore” and “Midnights.” The film’s storytelling succeeds most wildly when the artist interacts in Broadway style stage productions such as the heavily choreographed “Last Great American Dynasty” set in a seaside home with festooned revelers or aboard the illuminated chess board of “Mastermind” with other dancers as pawns she has slyly controlled. The depth of field in the film format also enhanced intimate narratives such as “Tolerate It” depicting a dissolving relationship between two lovers across a long dining table — with lots of glass to break. Much of the spectacle is truly like an expanded halftime show style greatest hits extravaganza as dancers joyfully move to the grooves of “22, “Love Story,” or “Shake It Off.” The zigs and zags make the through-line a little labyrinthine to follow for the casual fan, but you get your money’s worth plus there’s plenty of room for a bathroom break when non-Swiftie guests just need to calm down. Taylor also delights in confessional piano numbers like “Champagne Problems” and “You’re On Your Own, Kid,” evoking superstars who can command a Madison Square Garden type atmosphere. Some fan favorites like “Delicate” and “All Too Well” didn’t benefit as much from more straightforward staging but still provoke a reaction. The musicians and dancers shine brightly, and so do the fans, who are in an unspoken (actually sometimes spoken) dialogue with the singer on stage. This unexpected documentary is a chronicle of an artist at the height of her power and enters the pantheon of legendary concert films.
