'Dolly Parton's Mountain Magic Christmas'
Parton serves up plenty of cheese in this old-fashioned holiday special, channeling the late Olivia Newton-John in a "Grease" parody and trading stale jokes with an angel played by Willie Nelson. Those moments are pretty awful. But the 76-year-old legend eventually ditches the ridiculous production numbers for some stripped-down spiritual numbers, including a moving hymn with Miley Cyrus and a solo version of "Hello God," which she wrote in the wake of the Sept. 11 attacks. "I hope I haven't crammed God or Jesus down anybody's throat," she says before a triumphant finale. Atheists who worship country music won't mind a bit. 8 p.m. ET Thursday, NBC; Peacock
