This has been a good year for Taylor Swift: The jokes about her various exes were finally played out, last year's Red continued to sprout hits, and she emerged, with that album's capital-e Extravaganza, as one of the most compelling arena acts of her generation. The category isn't labeled Best Arena Show Ever!!!, but it's close enough — in late May, a swarm of astoundingly polite, well-dressed, self-confident 9-year-old girls swarmed around Westgate's mock downtown, making perfect eye contact and feeling empowered. And, granted, making signs covered in high-contrast glitter. Taylor Swift's brand of hyper-produced, absurdly expensive arena show hasn't launched as many culture-studies Ph.D.'s as Lady Gaga's, but it's even more likely to feature an extended dance synthesis of dubstep, parkour, and the fashions of medieval Europe. And the kids it brings out are a little more likely to make you feel like the world is going to be a better — if also a more unnecessarily giddy — place when they grow up.
