Scorsese’s more narrowly focused version takes stock of those tectonic shifts in our nation’s history, but only in passing. This “Killers of the Flower Moon” doesn’t ebb and flow so much as it seeps out from the ground and pools in a small handful of different places. What Roth’s adaptation does allow is for “Killers of the Flower Moon” to blossom into a compellingly multi-faceted character study about the men behind the massacre. Mollie’s first-act flirtation with Ernest finds “The Killers of the Flower Moon” at its most agile and alive, with Scorsese firing on all cylinders as his movie explodes out of the gate. Grade: B+“Killers of the Flower Moon” premiered at the 2023 Cannes Film Festival.
