Several network shows air their season finales in the week of Dec. 17, and cable is largely taking it easy on original programming. Streaming services, however, are serving up a host of series and specials to carry users through the holidays.

Below is The Hollywood Reporter's rundown of some of the coming week's highlights. It would be next to impossible to watch everything, but THR can point the way to some worthy options. All times are ET/PT unless noted.

On broadcast…

Finale: Timeless returns for one night (8 p.m. Thursday, NBC) with a two-part series finale that will wrap up the cliff-hanger that ended season two before it was canceled.

More finales: The Voice (9 p.m. Tuesday, NBC), Survivor (8 p.m. Wednesday, CBS) and Murphy Brown (9:30 p.m. Thursday, CBS) finish their runs; the first two will be back for new cycles later in the season.

Special: The first-ever full-length Simpsons episode, "Simpsons Roasting on an Open Fire," re-airs on Fox (8 p.m. Sunday) as the network celebrates the show's 30th season. It originally aired Dec. 17, 1989.

On cable…

Special: Full Frontal With Samantha Bee celebrates the season with "Christmas on I.C.E.," which will also raise money for the family separation response team KIND, an organization helping unaccompanied children in the U.S.

Documentaries: Bleed Out (HBO, 8 p.m. Monday) looks at a family's struggle with the American health-care system; director Antoine Fuqua examines Suge Knight in American Dream/American Knightmare (8:30 p.m. Friday, Showtime).

Returning: Marvel series Runaways launches its second season Friday on Hulu, with the superpowered teens adjusting to life as, uh, runaways and plotting to stop their evil parents.

Special: Relatable, Ellen DeGeneres' first stand-up special in 15 years, drops Tuesday on Netflix.

In case you missed it…

Chilling Adventures of Sabrina begins its second season in April. To tide you over, the holiday special Chilling Adventures of Sabrina: A Midwinter's Tale brings Sabrina (Kiernan Shipka) and her fellow dark-arts practitioners together to celebrate the winter solstice. It's streaming on Netflix.
