The coming-of-age drama “So B. It” is an odd duck, a mix of 12-year-old quirky optimism and grown-up anxieties that never come together in a complete story.
This adaptation of Sarah Weeks’ young-adult novel centers on Heidi It (played by Talitha Bateman, last seen in “Annabelle: Creation”), a 12-year-old living in Reno, Nev., with her autistic mother, So (Jessica Collins). So paints childlike pictures, speaks only 22 words and is incapable of caring for herself. Heidi and So live with a guardian, Bernadette (Alfre Woodard), whose acute agoraphobia keeps her from leaving their shared apartments without debilitating panic attacks.
