At nearly 30, Megan (Keira Knightley) is emotionally careless and still treading water in suburban Seattle. But a chance encounter with Annika (Chloe Grace Moretz), a teenager looking for an older female in her life, provides the impetus for Megan to finally grow up. Or perhaps not, since Megan really digs regressing back to teen-age hang-out behavior, though her adult side is intrigued by Annika's acerbic dad (Sam Rockwell). Lynn Shelton's double-header coming-of-age tale is sweet, funny and frequently insightful. The three leads all deliver engaging and believable performances, though it's hard to salvage some of the rom-com clichés that bog down the final reel. But don't let the eye-rolling ending stop you from enjoying this fun little character study.
