Billie Eilish has had an unbelievable couple of years, to put it lightly. R.J. Cutler’s mammoth of a documentary follows the ins and outs of the 18-year-old musician’s meteoric rise that puts her feelings at the forefront. The World’s A Little Blurry follows Eilish through the most pivotal years of her career—and her teenagehood—but she is able to speak for herself when she has so often been spoken over, spoken about, and over-speculated. Cutler graciously weaves between Eilish’s public and private lives and reveals just how blurred those lines become with fame—and how emotionally taxing that can be for a young teenager. The World’s A Little Blurry is most captivating, though, when it peels back the curtain on her mental and physical health: flipping through personal pages of her diary, gritting her teeth through necessary physical therapy, feeling bombarded and used by people just trying to control her. But between the glitz of her sold-out tours and historic Grammy wins, the film is equally concerned with who she is outside of all that: a teenager. She records music in her bedroom with her brother, she fangirls over Justin Bieber, she gets her driver’s license—she just also happens to be one of the biggest pop stars in the world.
