20 Best Movies on Starz Right Now

That this film, an adaptation of a beloved classic and girlhood staple for 50 years and counting, is able to retain the same power, charm, and wisdom as the source material by Judy Blume is impressive in and of itself. 

Director Kelly Fremon Craig (Edge of Seventeen) turns the must-read novel into a must-see film, as urgent and relevant as ever in its frank portrayal of feminine woes and joys. Buying your first bra, getting your first period, losing a friend, doubting your faith, seeing—really seeing—your family for the first time, and knowing in your heart what you stand for...these are some of the thorny requisites of womanhood, and Craig navigates them with a bittersweet ease that never feels pandering nor patronizing. Like the book, the film honors this young person's big feelings by centering them in a sprawling story that involves other characters, who are just as fleshed-out as the lead. Rachel McAdams deserves special mention for turning in a sweetly nuanced performance as Margaret's mother Barbara, an artist attempting to balance her domestic role with her career goals. 

The film may be 50 years in the making, but it tells a timeless tale that will continue to hold the hands of teenage girls for generations to come.
