It's a big week for spring premieres, including a hotly anticipated new horror series from Showtime.

Penny Dreadful, which will bring us a realm of horrors from Victorian London, hits our screens this week with its premiere Sunday night, but it's not only the big premiere on our radar in the days to come. We've also got the first part of NBC's new Rosemary's Baby miniseries and the return of the acclaimed BBC zombie series In The Flesh. Plus, The Tomorrow People and Once Upon a Time both end their seasons, Ward's past comes to light on Agents of S.H.I.E.L.D., the team gets sucked into a soap opera on Warehouse 13, and a trial begins on Game of Thrones.

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

Highlights of the Week

The Tomorrow People (The CW) Monday, 9 p.m. - "Son of Man"

Season finale! - The Tomorrow People is one of several shows -- alongside things like Star-CrossedThe Originals and The 100 -- The CW rolled out for the 2013-2014 TV season to make the network even more genre-driven than it already was. That commitment to genre TV is set to continue next season in the form of pilots for shows like The Flash and Supernatural: Bloodlines, but of course, some of these shows will fall by the wayside. From the beginning, Tomorrow People was one of the more intriguing new genre series on network TV this season, thanks in part to its ties to the classic British series on which it's based, and while it's certainly maintained a solid core of fans, its ratings decay over the past few months means this season finale could be a series finale. Even if this is it for The Tomorrow People, though, it'll stand as a testament to The CW's ambitions to keep trying out genre TV in its various forms, and that's always something worth paying attention to. In tonight's episode, Stephen fights to stop the Founder's Machine, Russell rethinks his alliance with the Founder, and Jedikiah has an offer for John. Check out a preview below:

In The Flesh (BBC America) Saturday, 10 p.m. - "Episode 1"

Season premiere! - Even if you're tired of zombies, a show like In The Flesh might just pull you out of that particular subgenre slump. The first season of this zombie rehabilitation drama drew acclaim for its clever premise, and now that premise is expanding into new territory with a second series that's twice as long as the first. As prejudices against the PDS survivors continue to flare, the Undead Liberation Army is ready to retaliate, and many PDS survivors are eager to hear the Undead Prophet's message of a "Second Rising," a new breed of undead that will perfect what the first rising started. At the center of it all, though, is PDS survivor Kieren, who just wants to get on with his life. Season two promises to be an intriguing mix of conflicts and questions, and it all begins this week. Check out a preview:

Rosemary's Baby (NBC) Sunday, 9 p.m. - "Part 1 of 2"

Miniseries premiere! - NBC's taken some intriguing gambles when it comes to event programming lately. First we got a live broadcast of "The Sound of Music" late last year (and more live musicals are on the way thanks to its success), and now we've got Rosemary's Baby, a new adaptation of Ira Levin's classic thriller that stars Zoe Saldana as the titular Rosemary Woodhouse and moves the action from Manhattan to Paris. New adaptations of old source material are not surprising these days, but the risk here lies in the fact that Rosemary's Baby already has a truly iconic adaptation in the form of the classic 1968 horror film by Roman Polanski. For many fans, Mia Farrow simply is Rosemary, thanks to her performance in that film, so to say Saldana has big shoes to fill might be an understatement. Still, moving the story across the Atlantic is an intriguing start to this version of the tale, and if it can continue to give us enough fresh twists on this classic story, this miniseries just might be one of the year's most pleasant TV surprises. Check out a preview below:

Penny Dreadful (Showtime) Sunday, 10 p.m. - "Night Work"

Series premiere! - It was a pretty good time to be a TV horror fan already, thanks to hits like The Walking Dead and American Horror Story, but now the much-buzzed-about Penny Dreadful is here to scratch a different kind of horror itch for us all by delivering a Gothic tale of mystery and violence in the heart of Victorian London. Trailers for the series have proven fiendishly, deliciously evocative of a certain kind of sexy, monstrous horror tale, one full of dark, misty nights and fireside conspiracies. The cast -- which includes Eva Green, Josh Hartnett, Timothy Dalton and Billie Piper -- is easy to get excited about, and the still-mysterious story -- which will somehow tie together Dr. Frankenstein, Frankenstein's monster, Dorian Gray and other classic weird Victorian characters and tropes -- suggests a web of curiosities that we could very easily and happily get lost in. Now it's time to find out if the series lives up to all this hype. In the opening episode, a series of gruesome murders grips London, and Sir Malcolm Murray (Dalton) and Vanessa Ives (Green) are convinced something darker than mere human violence is in play. Check out a preview for the series below, and if you just can't wait to see the premiere, go watch it for free online right now. 

Once Upon a Time (ABC) Sunday, 8 p.m. - "Snow Drifts" & "There's No Place Like Home"

Two-part season finale! - Once Upon a Time is a show that never stops throwing new hooks at its viewers, and season three has proven that time and time again. The show has gone from Neverland to Oz to New York City and back to its home base of Storybrooke over the past few months. New characters have been introduced, new threats have been conquered, and now the show is primed to take its heroes on a new adventure in yet another magical place. But where will they go? For many viewers, finding out where events will unfold next and which new characters will be roped into this saga has become almost as exciting as finding out exactly what will happen, and that's made Once Upon a Time addictive on multiple levels for its devoted fans. Season three has been its most ambitious yet, but part of the allure of this massive finale is finding out not just where season three ends, but where season four will begin.
