The entire book lacked a sense of purpose. It's a clutter of information, which oftentimes contradicts itself, that appears to have no aim. It feels like the rough draft of a thesis, with a bunch of sources thrown about, misinterpreted, and lacking cohesion.
While it supposedly tells the story of Chris Knight, there was nothing in the story that allowed readers to empathize with him or anyone else. The author talks a lot about himself, though never really humanizing himself either, and his experiences trying to talk with Knight. I found it particularly odd how ardent he was to communicate with Knight, calling all Knight's family members and showing up unannounced after the man clearly expressed his desire to be left alone. He provides no reasoning for this, really no emotional details about himself at all.
