Courtney Howard The growing pains and dramatic throes of girlhood can be character building, traumatic, and cathartic — for both cinematic protagonists and their audience. It’s certainly not an easy time for the heroine at the center of “You Are So Not Invited to My Bat Mitzvah,” whose impending rite-of-passage ushers in an adulthood she’s not quite ready to handle. Director Sammi Cohen and screenwriter Alison Peck bestow this hilarious, heartrending adaptation of Fiona Rosenbloom’s novel with an uplifting, effervescent vision and vitality, giving voice to a young Jewish girl’s struggle to figure out who she is before the most important night of her life so far.
