This is one of those extremely unique cases in criminal history. Elements of Kaczynski's life and mentality feel very commonplace in many of today's movie villains, but to see how meticulously he planned and kept himself off the government's radar for the sake of committing these crimes, regardless of his motivation, is truly unnerving. Glad they gave his brother and sister-in-law the chance to shed light on their part in this tragic tale.
