Nothing Compares weaves a poignant story about one of the most misunderstood artists of our time, Sinéad O’Connor. The iconoclast first made waves in the '80s with her catchy music, but she quickly reclaimed the reins of her own fame and used her platform to champion marginalized causes, long before pop stars were expected to do so. The documentary zeroes in on this part of O’Connor's life: what prompted her to music and how she used it as a tool of activism. The answers are multi-faceted and handled here with extreme grace. Like the many from her generation, O’Connor struggled with religion and abuse, such was the Catholic Church's hold on Ireland at the time time. The film contextualizes her once-shocking moments and reveals how they were all grounded on things she cared about. It’s a beautiful piece of work that reassesses and redeems a wronged artist who was ahead of her time.
