American Primeval is the most authentic, grittiest, meanest, bloodthirsty, gripping, and fascinating western since 2015's "The Revenant." I watched all 6 episodes non-stop, my advise is to set aside a 6 hour block of time because you will be transported to Utah in 1857 and won't want to leave.
American Primeval was written by Mark L. Smith, he and Alejandro G. Iñárritu wrote the revenge saga “The Revenant,” the brutality is similar.
The story follows Taylor Kitsch as a mountain man guiding a mother and son, played by Betty Gilpin and Preston Mota through the unsettled Utah wilderness surrounded by the Church of Jesus Christ of Latter-day Saints formed militias, the US Army, very pissed-off Indians and murderous bounty hunters, all trying to claim Utah for their own and not hesitating to kill anyone who stands in their way. The action is put in motion by the real-life Mountain Meadows Massacre, in which church militia members slaughtered some 120 members of an emigrant wagon train.
