I've done multiple deep dives into historical writings and books. Jon Krakauer's book is well reflected in the first two episodes released. From what I have found the book is accurate to an acceptable degree of what actually occurred in the Lafferty case, and the show appears to be on the same course. Please don't let the negative reviews of jumpy religious zealots deter you from an intricate true crime show, based on an intricate true crime book.
