Judy Blume published "Are You There God? It's Me, Margaret" way back in 1970. 53 years later, director Kelly Fremon Craig adapts the story into this gorgeously fun, bright, and heartfelt film. Abby Ryder Fortson navigates Margaret's life with wide eyes that see and judge everything, and Rachel McAdams seems effortlessly wonderful as Margaret's mom, who's struggling to find her own identity as her only child grows up right in front of her eyes. It's heartwarming but not overly sweet, and still leaves in all the sticky, complicated questions that Margaret will spend a lifetime trying to wrap her head around.
