Now we have reams of first-person digital footage, which means that viewers, more than ever, are privy to the perspectives of those directly involved, often during the period in which the crimes took place, closing the distance and making the intermediaries less essential. The case of Gypsy Rose Blanchard encapsulates the trajectory of this phenomenon. Her saga, for example, received the scripted treatment with “The Act,” a 2019 limited series on Hulu, for which Patricia Arquette won an Emmy. But those looking for a definitive, unvarnished, visceral take on the events now have options and direct channels, rendering that series as almost an afterthought.
