Sometimes the biggest catastrophes leave no mark. The 1918 pandemic killed about 675,000 Americans, but left hardly a ripple in the cultural consciousness. It was forgotten by many until the outbreak of COVID. However, given the number of COVID-related projects already in the works (Jenji Kohan’s lockdown anthology “Social Distance,” among others), this is one disaster that feels like it will be fully memorialized. One would think, given the reams of articles and many topical movies on the Great Recession (“The Big Short,” “Inside Job,” and so on), that the crisis had been appropriately covered for future generations. However, according to Patrick Lovell and Eric Vaughan’s enraged and enraging miniseries “The Con,” pretty much all of those works aimed too small.
