I just finished listening and the podcast (spoiler) reminded me of nothing so much as the concept of the Speaker of the Dead from Orson Scott Card's Ender's Game and sequels. This is a religion/calling of people who learn everything they can about a dead person, try to solve their mysteries, and then tell an unbiased but sympathetic account of their life. I thought the podcast was extraordinary and highly recommend it.
