Framed as investigative journalism but presented as darkly humorous entertainment, “To Catch A Predator” ran for just 20 episodes. The movie makes extensive use of unaired, behind-the-scenes footage from “To Catch A Predator,” including from police interrogation rooms. Disgraced financier Epstein was convicted of sex offenses and found dead in his jail cell while awaiting trial on allegations of sex trafficking underage girls. US President Donald Trump, once a friend of Epstein, has tried to quell the calls to release the Epstein files — despite attacking opponents with them in the past. Yet the biggest root of our obsession may be the seemingly clear-cut morality these shows serve up.
