Dir/Screenwriter Taylor Sheridan's "Wind River" Stars Jeremy Renner but Fails to Deliver a Winning Script

Taylor Sheridan (b Amer 1970) is an actor, dir. screenwriter.  His exceptional screenplay for the exceptional multiple Acad Award nominated film "Hell or High Water" & earned an Oscar nom. for best original screenplay.  "Wind River" is a murder mystery set on an Indian reservation in Wyoming.  The film's stars Jeremy Renner, Elizabeth Olsen & Graham Green all deliver superior performances.  The supporting cast is also outstanding.  The 2 stunning actresses Julia Jones ("Twilight Series") & Kelsey Chow ("Spider Man") are both wonderful in their roles.   The cinematography of the frozen tundra of the barren reservation is splendid.  The landscape is captured in all its harsh, frigid beauty.  It's Sheridan's flawed script which fails to be convincing or emotionally riveting.  Cory Lambert (a terrific Jeremy Renner) is a Wild Life Service Agent.  He discovers the body of a young woman (Kelsey Chow) from the reservation who was the best friend of his daughter.  Lambert's own daughter was murdered 3 years prior.  The mystery of what happened to Lambert's daughter, Wilma (Julia Jones) was never resolved.  FBI agent Jane Banner (a sensational Elizabeth Olsen) is assigned the case & enlists Lambert for his tracking expertise.   The Sheriff on the reservation (the incomparable Graham Green) is sorely understaffed & overburdened by the limited opportunities afforded the people of his community.   The outline of the plot showed promise.  The family members of the 2 murdered girls evoke our sympathy for their grief.  Sadly, the big blowout is an overwritten high noon shootout.  Everyone is shooting at everyone else.  It becomes too difficult to track.  The flashback to the events prior to the young girl's death cuts so abruptly into the story that it kills off the  intrigue.  Sheridan wrote a first rate script with "Hell or High Water" but "Wind River" doesn't hold water.   The story gets lost in drifts.
