Sing Street: John Carney is operating under the near-certainty that music and nostalgia are sure-fire ways to emotionally affect the public; and, oh boy, do they ever in this lovely little film. The story is simple enough, but it does have lots to say about its setting, including the musical scene at the time. But the true reason why the film resonates as it does is the acting of the kids: they are all very charming, and the central couple, played by Lucy Boynton and Ferdia Walsh-Peelo, is simply marvelous. The adults are not far behind, Jack Reynor being the highlight. The period reconstruction looks very good, and the locations chosen reinforce that. The music is well-chosen, both the licensed songs and the original ones (which are well-performed by the kids).
