Faithless to the source material

SOOOO sick of adaptations of books that I loved but which completely change key aspects of the main characters. Has been many years since I read all the Hillerman novels, but even after all that time, I recognize the character of Jim Chee is NOTHING like in the books (and was badly mis-cast as well). Not only that but completely eliminates pretty much all of the internal conflicts that he struggles with and which both propel the narrative and relate aspects of Dine' culture. In the books he was NOT an FBI agent and was struggling with whether to become one and he was studying to become a medicine man not disrespectful of Navajo religion and traditions as in the series. And WHERE TF did the plot come from??? Certainly not any of the books *I* read. Was really looking forward to this series; what a disappointment. This seems more like a bad re-make of Thunderheart but with the names of Hillerman's characters.
