I appreciate the historical contexts and stories first of all. I also appreciate that Amy and Adam do their due diligence and encourage investigators to research any lead or information they receive. The writers describe events in which there is irrefutable evidence of spirits, but they also tell the reader about the hoaxes that have come up over the course of history dealing with spirits and paranormal activity. Lastly, readers can appreciate that Amy and Adam provide tools, equipment suggestions, and best practices needed to communicate with spirits.
