The end of the year often means the end of some of our favorite shows, and on December 14, 2021, our guide to what to watch tonight will bid farewell (for now) to several, starting with the fall finale of "Riverdale" season 6 and the season 21 finale of "The Voice."

Our list highlights some top picks and a brief roundup of what else is new on TV tonight. We also recommend some shows to watch this weekend.

Here's what's new on TV tonight, as well as shows and movies that just became available on streaming services. Click here for streaming service recommendations.

Tonight's new episode of "Riverdale" is a big one. It is the 100th episode of the series, the fall finale, and the conclusion of the supernatural "Riverdale" episode that brought Sabrina Spellman (Kiernan Shipka) to town.

Jughead (Cole Sprouse), unnerved by the strange series of events happening around him, sets out on a journey to find answers that will reveal the truth about Rivervale. The show uses this opportunity to call back to its comic book roots. As creator Aguirre-Sacasa told EW, "The show lives in the tension between what people think of as Archie Comics and its darker, sexier, more violent version. But I love comics, and what if we made our 100th episode about it?"

"The Voice" Season 21's roller-coaster ride is almost over. Tonight's finale will feature a dead heat between Team Blake, Team Kelly, and Team Legend (Ariana Grande, sorry). The top five performers performed last night, singing "The Chain" by Girl Named Tom (Team Kelly), "Rolling in the Deep" by Jershika Maple (Team Legend), and "Over the Rainbow" by Wendy Moten (Team Blake). by Wendy Moten (Team Blake).

Wendy really got things going last night, but we're still betting on Girl Name Tom. They were the first trio to perform in the finale, and the Lichty siblings not only have great voices, they blend well together.

Also performing in the finale will be Alicia Keys, Carrie Underwood, Coldplay, Ed Sheeran, Walker Hayes, Tori Kelly, and Keke Palmer.
