Actor Jean Smart chews up the scenery in everything she does. I loved her in “Designing Women” decades ago and, more recently, in “Mare of Easttown.” Now I’m loving her in HBO Max’s comedy drama, “Hacks,” as a Las Vegas comedian in danger of losing her longtime residency at the Palmetto Casino. Her agent pairs her with a struggling young comedy writer to give her act some juice and the duo clash with flying colors. — Jennifer Mulson, The Gazette
