SPECIAL PREMIERE: Netflix started by generating original series – for adults and for children. Then it added TV movies and miniseries, and also has elbowed its way, quite forcefully, into the area of television specials. Standup comedy specials and music concert specials, long part of the territory claimed by HBO and Showtime, are now being mounted, quite forcefully, by Netflix as well. This morning, Netflix dropped this new filmed-for-posterity version of Taylor Swift’s recently completed U.S. Reputation stadium tour. It was performed and recorded at the tour’s final stop, in Dallas, and mixes the spectacle of a stadium show (mega-TV screens, giant snakes looming as part of the stage set, lots of choreography and costume changes) with a one-woman showcase (just the singer-songwriter, her guitar, and tens of thousands of fans, singing along to every word and illuminating the crowd by filming on their individual smartphones).
