There's not a lot of new TV this week, but there are plenty of marathons and a couple of sci-fi Christmas specials to tide us over.

It's Christmas time again, and for many of us that means we get to return to the TARDIS with the Doctor Who Christmas special. Plus, a new Black Mirror Christmas special, plenty of marathons, a new episode of The Librarians and a few more fantasy holiday specials for the whole family.

Check out the week in TV below. What's on your watchlist?

Highlights of the Week

Usually we feature five highlights in this section, but it's Christmas week and we're a bit light on new TV, so we're trimming things a bit. 

Marathons! (Various channels and shows)

In addition to the mandatory 24 hours of holiday classic A Christmas Story that will air this week, plenty of genre shows will be rolling out marathons of their own, so if you want to catch up on some shows, get a taste of some you've never watched, or just see some old favorites again, it's a good week for that. Tonight Disney XD will air all four most recent episodes of Star Wars Rebels beginning at 9 p.m., so if you've been waiting to catch up on that show, now's the time. Tomorrow BBC America will host an all-day Star Trek: The Next Generation marathon beginning at 8 a.m. Wednesday it's Doctor Who time, as BBC America kicks off several days of time travel with a David Tennant marathon at 8 a.m., followed by a Christmas special marathon at 1 p.m. If that's not your thing on Wednesday, head to Syfy and watch the whole first season of Jim Henson's Creature Shop Challenge beginning at 10 a.m. Then, on Thursday, when you're not unwrapping gifts and stuffing your face, you can catch a marathon of Peter Capaldi's entire first Doctor Who season on BBC America beginning at 8 a.m., or you can watch a whole bunch of winter-themed original movies on Syfy beginning at 9 a.m. Post-Christmas, you can catch another Doctor Who marathon, this time of the David Tennant years, on BBC America beginning Friday at 8 a.m., a Harry Potter movie marathon on ABC Family beginning at 7 a.m. Saturday and continuing at 8 a.m. Sunday, and an Outlander marathon beginning at 3 p.m. Saturday. Having trouble keeping all of that straight in your head? Don't worry, it'll all be listed in order in the schedule below.

Doctor Who (BBC America) Thursday, 9 p.m. - "Last Christmas"

Christmas special! - At last, the time has come for Peter Capaldi's first Christmas special in the TARDIS, and after you've finished with all your holiday madness on Thursday you can cozy up on the couch and see what happens. Capaldi's first season as the Doctor was an interesting and divisive one for fans, many of whom were quite happy with Capaldi himself, but not so happy with the storytelling decisions made by showrunner Steven Moffat. This time around, though, focus is less on Moffat and more on the fate of Jenna Coleman's Clara Oswald. Clara had a lot more to do in this past season, sometimes even posing as the Doctor and saving the world herself, but rumors have persisted for months that Coleman is nearing the end of her time on the show, and while Capaldi has publicly been confirmed for another year, she has not. Now, that certainly doesn't mean she's going anywhere. In fact, it might simply be the show's way of keeping us guessing until we know for sure, and if that's the case, it's working. Either way, we'll find out this week whether Clara stays or goes when she and the Doctor must team up with Santa to battle monsters at an arctic base. Check out a preview below.

Black Mirror: White Christmas (DirecTV Audience Network) Thursday, 9:30 p.m. 

Christmas special! - Over the last few weeks, plenty of American viewers have discovered the acclaimed British sci-fi anthology series Black Mirror, thanks to its arrival on Netflix's streaming service. The show's varied, but always compelling and often disturbing, takes on the darkest parts of technology in our lives have led it to be one of the Internet's most talked-about shows, and now we can experience more of it with the 2014 Christmas special, which will make its way to American shores via DirecTV. Unfortunately, that means you either have to be served by that particular satellite provider, or know someone who does, to see the special on Christmas Day, but if you're into the show it's nice to know you can find a way. In this year's special, two men (Jon Hamm and Rafe Spall) working at a small outpost in an icy wilderness discuss their work and share Christmas, and their conversation becomes the framework for three mini-stories. Check out a preview below.
