TV THIS WEEK: Galavant premieres, marathons galore, and more!

If you just want to sit on the couch and watch a lot of familiar genre TV, this is the week for you.

Most of our current shows are still on holiday break, and we'll have fun premieres soon, but this week is largely quiet on the new TV front. That's OK, though, because that leaves plenty of room for lots and lots of marathons, including every episode of The Walking Dead so far. Plus, ABC premieres its new fantasy comedy GalavantResurrection returns, and more.

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

Highlights of the Week

Since we're still in the midst of holiday madness, we're a bit light on highlights this week, but there's still plenty to get excited about.

More Marathons! (Various networks and times)

Most of our favorite shows are still on break, and this week we don't even have Christmas specials to look forward to, but that doesn't mean we're short on stuff to watch. Various networks are still flooding us with our favorite genre programming through marathons, and whether you're looking to catch up on a currently airing series or revisit some old classics, you'll probably find something you like if you look around a bit. In the listings below, we've got everything from Syfy's annual Twilight Zone marathon to a chance to catch up on Z Nation to a four-day push through pretty much every episode of The Walking Dead. You'll find it all listed by day below.

Galavant (ABC) Sunday, 8 p.m. - "Pilot" and "Joust Friends"

Series premiere! - This week, ABC will give us a genre series unlike anything else on TV right now, a musical fantasy comedy from creator Dan Fogelman (Cars and Cars 2) and songwriters Alan Menken and Glenn Slater (Tangled). The eight-episode series will air for four weeks in January, and tells the tale of Galavant (Joshua Sasse), a brave but somewhat disillusioned hero who seeks to reclaim his love Madalena (Mallory Jansen) from the evil King Richard (Timothy Omudnson). Footage from the series so far paints it as a very self-aware, silly take on a fantasy quest, complete with musical numbers and guest stars ranging from Weird Al Yankovic to Rutger Hauer. The silliness might end up grating, but it also might win us over. Check out a preview below.

Resurrection (ABC) Sunday, 9 p.m. - "Prophecy"

Midseason premiere! - For some shows, a midseason finale means quite a long break, but for Resurrection it meant less than a month. It's the first major broadcast series to return from its 2014 break, and it's got some ground to make up for if it hopes to stick around for season three. Last season, the show was a spring hit for ABC, with a premiere that drew nearly 18 million viewers and a run of eight episodes that never drew less than 10 million viewers per week. This year, people seem to just keep dropping the show, and the midseason finale on Dec. 7 drew fewer than 4 million Live+Same Day viewers and few than 6 million total viewers. On another network, that might not seem so bad, but for an ABC series with a prime Sunday night timeslot, it's not good news. Resurrection might still have a chance to turn things around, but if it doesn't, season two could be the end. This week, a storm knocks out power, and Jacob and Margaret go missing.
