Wild Rose ★★★½

A winsome crossover between the social-realism of Ken Loach and the country spirit of Kacey Musgraves, Tom Harper’s “Wild Rose” might follow the familiar melodies of a fish-out-of-water crowdpleaser, but this story of a delinquent Glasgow woman who dreams of singing at Nashville’s Grand Ole Opry still manages to sound unlike anything you’ve ever heard before. Credit for that belongs to the ridiculous talent of Jessie Buckley, whose unbridled lead performance builds on her work in “Beast” and “Chernobyl” to confirm the young Irish star as one of the most exciting people you could ever hope to see on a movie screen.

There may be an off-the-rack quality to the film around her, as Nicole Taylor’s script doesn’t quite thread the needle between blue-collar drudgery and fairy tale plotting — it’s hard to fit an ankle monitor into a cowboy boot — but Buckley wears her role like it’s covered in sparkly rhinestones that nobody else can see. She’s a force of nature in every scene, but your heart stops beating whenever she starts to sing. No matter how contrived or hackneyed things get, Buckley’s voice always breaks through the clouds like some kind of divine revelation. And that voice only gets more powerful when “Wild Rose” finally gives it something to say.
