A film powered by a mesmerizing performance from a young up-and-comer, “Wild Rose” is a Scottish-infused ‘Star is Born’ with a blue-collar tinge added for good measure and grit. Directed by Tom Harper, the film tells the story of Rose-Lynn (Jessie Buckley), a Scottish 20-something lass who happens to love country music; so much so, that she intends to find enough money to go to Nashville and pursue her dream of becoming a star. It doesn’t help that she must also grapple with having just been released from jail (for a minor crime) and is the young mother of two children. Harper tries to build up his clichéd underdog story into something fresh and incisive. The tropes are, sadly, all still there, but with the help of Buckley’s passionate performance, “Wild Rose” succeeds because it never forgets that, sometimes, life can get in the way of your dreams.
