Emma Seligman makes an impressive filmmaking debut with “Shiva Baby,” managing to tap into a mounting sense of panic in a way that rivals seasoned helmers. The writer/director doesn’t go big for his first feature, taking viewers into the pressure cooker environment of a funeral gathering, with Jewish families coming together to mourn, but also catch up on gossip and personal achievements, leaving the central character to manage all sorts of judgmental attitudes while dealing with a potentially life-changing reveal of her secretive employment. Offered a house filled with itchy personalities, and Seligman transforms “Shiva Baby” (an adaptation of her 2018 short) into a remarkable suspense picture that’s loaded with amazing performances and turns of plot, keeping the endeavor riveting and also darkly comedic. Seligman does a lot with very little here, showcasing a gift for subtle behaviors and broad confrontations. Read the rest at Blu-ray.com
