"With uncommon stealth, Let Him Go morphs from a drama about loss and grief into a terrifying thriller."
— Glenn Kenny, The New York Times
"Watching Diane Lane and Kevin Costner connect as a couple determined to retrieve their grandson is pure movie heaven."
— Richard Roeper, Chicago Sun-Times
"Understated in its quiet rhythms and vast beauty, [Let Him Go] is fortified with strong performances and, eventually, punctuated by shocking moments of violence."
— Christy Lemire, RogerEbert.com
"It's just a genre movie that delivers the goods, but the restraint and emotional insight of the direction and the quality of the performances bring it up an essential extra notch."
— Mick LaSalle, San Francisco Chronicle
"Succeeds both as a low-key character study and as a breathlessly intense thriller about the clash between good (but not perfect) people and bad people, none of whom are to be trifled with."
— Alonso Duralde, TheWrap
"Let Him Go wastes no time pulling you into an emotional grasp so compelling you can’t believe what happens as the narrative moves from one shocking scene to the next in a pandemic of violence."
— Rex Reed, Observer
"In many ways, it feels like the midcentury pulp thrillers it emulates: well-plotted and grisly, but almost ephemeral. It is Lane's performance that lingers, one that dares to be uniquely hopeful about the future, and letting the old ways die."
— Katie Walsh, Los Angeles Times
