In what may be one of the most brutally honest and visceral (and yet resoundingly inspirational) celebrity documentaries ever, we’re taken inside every facet of the struggling singer’s life as she lives each day battling stiff person syndrome. Acclaimed director Irene Taylor (and credit to Dion for providing the all-areas access) shows us every bit of the unflinching truth, up to and including a horrifying and heartbreaking seizure that Dion endures toward the end of the film. There’s no question that the singer is facing the literal battle of her life, but her perseverance and vulnerability will no doubt inspire and educate like no other documentary in recent memory.

4.5/5 stars
