TV THIS WEEK: Orphan Black returns, The Messengers premieres, and more!

We've entered that wonderful time of the year in which many of the shows that began in the fall are rolling out their season finale endgames, while at the same time midseason series are dropping their premieres. This week we've got several, including the series premiere of The Messengers, the season-three premiere of Orphan Black and the final season premiere of Lost Girl. Plus, Bitten returns, Gotham's back after a long break, and team-ups on The Flash and Arrow.

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

Highlights of the Week

Major Lazer and Axe Cop (FXX) Friday, 12 a.m.

Series/Season premiere! - If wacky genre animation is your jam, this is a good week for you. Remember the Animation Domination block of cartoons that used to air on FOX? Well, this week it makes the jump to FXX, where it'll premiere a brand new hour of 'toons, and there are two in particular that caught our eye. First, there's Major Lazer, starring the electronic music group of the same name, which gets its series premiere this Thursday night/Friday morning. It's about a Jamaican superhero fighting evil in a dystopian future, so you know you want to see that. Then there's the much-loved Axe Cop, adapted from the webcomic of the same name. That series is returning for its second season (with a different network this time), and there'll be more chaotic cop shenanigans to enjoy. Check out a trailer for Major Lazer below.

Bitten (Syfy) Friday, 8 p.m. - "Bad Blood" and "Scare Tactics"

Season premiere! - For a good while, Bitten fans weren't sure the show would get a second season, and the wait for news of a renewal got so long and so anxiety-inducing that, eventually, a Twitter campaign started to get Space (the show's Canadian home) to renew the series. Space finally did pick up season two, and only a week later Syfy announced that it would again bring the show to the States, so here we are. The season has already ended its run in Canada, but this Friday Americans get their first chance to see what's in store. Of course, plenty of werewolf drama, romance and passion can be expected, but the show's added a new wrinkle to its mythology this time around: witches. Will that deepen the story or just make it longer? We'll find out. Check out a preview below.

The Messengers (CW) Friday, 9 p.m. - "Awakening"

Series premiere! - The CW's riding a wave of renewed genre success lately thanks to shows like ArrowThe Flash and The 100, and the network is still trying its hand at new sci-fi and fantasy efforts. They don't all work, and the past couple of years alone have given us casualties like CultStar-Crossed and The Tomorrow People, but The CW definitely wants to keep courting a genre audience, and so this week they're launching The Messengers, a fantasy drama driven by prophecy and an epic clash between good and evil. It begins when an object crashes to Earth and sends out a shockwave that selectively kills five seemingly random people, who then miraculously come back to life. Clearly, they've been chosen for something, and apparently it's to fight an evil force that created the impact on the exact site where the first atomic bomb was tested decades earlier. The trailers lay out that particular backstory and the tribulations each of the five people face as they try to understand exactly what's happened to them, but the mystery remains. We'll just have to watch to see what that mystery is, and whether it makes for good television. Check out the trailer below.

Lost Girl (Syfy) Friday, 10 p.m. - "Like Hell, Part 1"

Season premiere! - Now that 12 Monkeys and Helix have completed their 2015 runs, Syfy's back to supernatural drama for a while, and that means Lost Girl is back for its fifth and final season. It seems like more and more these days we're getting genre dramas with planned, pre-announced final seasons, so rather than letting the show run and deciding if it'll come back at the 11th hour, showrunners have the chance to go out on their terms, whatever those terms might be. We saw it with Being HumanWarehouse 13Fringe and others, and now it's Lost Girl's turn. It's a bittersweet concept. On the one hand, you don't have hope of a renewal and another season beyond this one, but on the other you do have hope of a definitive ending. This week, Bo heads to hell to rescue a friend. Check out a preview below.

Orphan Black (BBC America) Saturday, 9 p.m. - "The Weight of This Combination"

Season premiere! - Orphan Black is not one of genre TV's biggest shows. It can't touch the audiences of a Walking Dead or a Game of Thrones or even a Gotham, but what this particular pop culture phenomenon lacks in size it more than makes up for in enthusiasm. The show's attention to detail and character, as well as the dizzying multiple performances of star Tatiana Maslany, have earned Orphan Black a rabid, and growing, following, and that following seems set to expand even more as we head into the third season. At the close of its second year, Orphan Black deepened and broadened its mysteries with the addition of male clones, something that makes season three not just a bigger story but a bit of a different animal, and it'll be interesting to see how creator John Fawcett and company navigate that. We've promised something big, so let's hope we get it. This week, Sarah continues her search for Helena. Check out a preview below.
