Even as it never fully justifies its existence,
McCarthy's character study of a mentally degenerating Tennessee hills outcast named Lester Ballard (Scott Haze) — abandoned as a child, now a grunting flouter of civilization — argues a view of humanity that makes nature vs. nurture seem pointless. The story, faithfully rendered by co-writer/director/Southern-gothic-aficionado Franco, graphically depicts Lester's feral descent from angry rifle-toting hermit and thorn in the side of the sheriff (Tim Blake Nelson) to romantically attached necrophiliac (after finding a dead girl in a roadside car, he makes a "house" with her) to, in the third act, full-on serial killer.
Haze's committed turn is a visceral tour de force, his guttural exhortations practically their own language, while Franco (who gives himself a brief cameo) has the narrative drive and smoky mix of poetic/primal backwoods imagery in lockstep. "Child of God" is a whole of sorts, but its source faithfulness and folksy grimness may seem too simplified overall to bring true impact to the psychological and physical horror on display.
"Child of God."
