Jeremy of The Daily Rotation wrote, "Billie Eilish: The World's a Little Blurry is an up-close-and-personal documentary, focusing on star Billie Eilish as she navigates the road to stardom and celebrity at such a young age, with the help of her supportive friends and family. Director R.J. Cutler keeps things feeling raw and undistracted as this lengthy film covers all of the bases."
