Ultimately, the entertainment industry documentary is here to stay because the contradiction is too juicy to abandon. We love the magic, but we are addicted to the unmasking. We want to see how the sausage is made, even if—especially if—it makes us sick. We want to believe in the star, but we need to confirm that the star paid a price we wouldn’t be willing to pay. The green room mirror doesn’t lie, but it does know exactly which angle to show you.
