Another overly sentimental “Christmas on the Square” (a ’20 Emmy winner) wallops another millionaire with conscience and spirit just in time. Great hillbilly country music, though. Another “Christmas Is,” now with gospel overtones. Jennifer Lewis dresses down the baddie with a real show tune: “Queen of Mean.” How to cure capitalism? “Everybody Needs an Angel.” (The angel is Jeanine Mason, who reports to the godly Dolly.) The pedantic showdown comes from Dolly with “Light Your Lamp,” a story no hard heart can withstand.
