Star quality. Who has it, and who doesn’t? Long before the trailer dropped for the forthcoming, ludicrously Oscar buzz-attracting remake of A Star Is Born starring Lady Gaga, that question has been hanging over this season of RuPaul’s Drag Race. That Ru has a very specific vision of what makes a star a star should come as no surprise to anyone who’s watched any of the show’s half-dozen or so burlesque dramatizations of her own underdog life. Ru’s diagnosis of star quality all but requires a razor’s edge of self-sabotaging doubt, a nefarious but fire-stoking internal voice that both keeps one self-aware but also driven to overcome. Without it, you’re merely talented.
