Stephen M’s review published on Letterboxd:
A Hollywood treatment of the Appalachian feud between the Hatfields and the McCoys, with a love story between a Hatfield son and a McCoy daughter being the catalyst for an eruption of the two clans' longstanding enmity. Mainly interesting for the cast and some stunning Blue Ridge Mountains photography, the script is not overly original and it doesn't really come together.
A major flaw is the young actress playing the lead character. Joan Evans was only 14 at the time of filming (her parents claimed she was 16 for legal reasons) and her acting range is limited. She apparently was a replacement for Cathy O'Donnell, as this was supposed to be a follow-up to her teaming with Farley Granger in the memorable Nicholas Ray film "They Live By Night". She's inexperienced; it's her first film and it shows. But even with the more seasoned O'Donnell, the script would still be uninspiring.
I did enjoy a host of great Hollywood character actors - Charles Bickford, Richard Basehart, Raymond Massie, Aline McMahon and Hope Emerson - doing a good job playing poor mountain folk. And the scenes of rural mountain life is convincing, with beautify scenery. It actually made me wish the studio had tried this as a color film, although that wasn't common for the period. Finally, watching it in a more enlightened #MeToo era, Granger's aggressive stalking and attempted rape of Evans in the first half of the film is treated way too casually, as is her apparent bliss after being literally abducted.
Overall a passable watch, but not a film worth a second viewing. I saw this streaming via the Watch TCM app.
