New TV Shows Released December 14-20, 2025
Here is a complete look at the new series and seasons that premiered in the middle of December.
“Percy Jackson and the Olympians” Season 2 (Disney+)
The hit fantasy adventure returned for its second season on Disney+. The series, based on the popular books by Rick Riordan, continues the story of young demigod Percy Jackson as he navigates dangers from ancient Greek myths in the modern world. The new season picks up with Percy and his friends facing fresh quests and monstrous enemies.
“Spartacus: House of Ashur” (Starz)
The gladiator epic “Spartacus” was revived on Starz with a new story titled “House of Ashur”. This series returns to the brutal world of ancient Rome, following new and familiar characters through the bloody politics of the arena. Fans of the original series can expect the same style of intense action and drama.
“The Copenhagen Test” (Peacock)
A new espionage thriller arrived on Peacock starring Simu Liu and Melissa Barrera. “The Copenhagen Test” follows agents navigating a complex world of international intrigue and suspense. The series promises high-stakes missions and unpredictable twists.
“Twelve Dates ‘Til Christmas” (Hallmark)
Hallmark Channel released a new limited holiday series led by Mae Whitman. “Twelve Dates ‘Til Christmas” is a festive romantic story set in the countdown to the holiday. It fits perfectly into the network’s schedule of seasonal programming.
Holiday Specials and Comedy
Several holiday-themed specials also launched last week. Netflix released “With Love, Meghan: Holiday Celebration,” a special featuring Meghan Markle and guests like Naomi Osaka sharing festive crafts, meals, and laughs. Comedian Matt Rife also dropped a Christmas-themed crowd work special on Netflix called “Matt Rife: Unwrapped”.
Final Episodes for Major Series
The week also saw fall finales for many popular network shows before their holiday hiatus. Series like “NCIS,” “FBI,” “Abbott Elementary,” “Ghosts,” and “Fire Country” aired their last episodes of 2025. This means no new episodes for these shows until they return in 2026.
Where to Watch and Catch Up
All the new streaming shows are available to watch on their respective platforms. You can find “Percy Jackson and the Olympians” Season 2 on Disney+, “Spartacus: House of Ashur” on Starz, and “The Copenhagen Test” on Peacock. The holiday specials “With Love, Meghan” and “Matt Rife: Unwrapped” are available for streaming on Netflix.
For the network shows that had their fall finales, viewers in the U.S. can typically watch recent episodes the next day on streaming services like Hulu or Paramount+, depending on the network.
