Personally, I like a certain genre of these bc they typically include a group of smart, caring people trying to solve problems and bring justice to the world. Criminal Minds was one I really liked. I think people who enjoy solving puzzles for relaxation, but who also have a dark side, might like these kinds of shows. I’m not trying to convince anyone, just explaining what some of us see in them.
A local duo has been making “the misery machine” podcast for a while now, and I hope they don’t burn out. I’m not a huge true crime fan, but I really like their work. They’re humane, often point out the failures of TPTB in letting this stuff happen, and seem to honor the victims.
ETA: they’re currently working on a series of child abuse cases in each state, which is bringing attention to the failures of our CPS system, and I applaud them.
