TV THIS WEEK: Powers premieres, Sif returns to S.H.I.E.L.D., and more!

After 14 years of waiting in some form or another, this week marks the premiere of Powers, the show about detectives hunting down super-powered criminals that's been in some form of development for what seems like forever now. That's easily the most exciting news of the week, but it's far from all we've got to look forward to. This week, Sif drops by Agents of S.H.I.E.L.D.The 100 has its season-two finale, we get five days of new Steven Universe episodes, and more.

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

Highlights of the Week

Steven Universe (TOON) Monday-Friday, 5 p.m.

Marathon alert! - If you're a fan of the world-saving Gem adventures of Steven Universe, this is going to be a very good week for you. The first season of the popular animated series is winding down after more than a year of broadcasts and more than 40 episodes (the final count will be 52), and for whatever reason Cartoon Network decided that part of that winding down would be a weeklong marathon of new episodes, one each night (two on Thursday) between now and Friday, before the final two episodes arrive on March 19 and March 26. The episodes will include a visit to a place once belonging to Steven's mother, Rose Quartz, a daring rescue of the other Crystal Gems and much more. Check out a preview below, and look for specific episode information in our main listings below.

Powers (PSN) Tuesday, Streaming - "Pilot"

Series premiere! - It's been a long, long road, but Powers is finally here. The first time anyone ever heard about an adaptation of the superhero police procedural comic from writer Brian Michael Bendis and artist Michael Avon Oeming, it was 2001, and no one had any idea just how long a wait the series had in store before finally making it to the screen. A pilot surfaced from FX back in 2011, but after lots of talk of reshoots, rewriting and even recasting, a show never materialized from that development. Now, at last, the show will arrive as the first-ever original series on the PlayStation Network. It's got a great cast (Sharlto Copley, Susan Heyward, Eddie Izzard and more) and a great look, and the early trailers have us really excited. Now we can finally see the whole thing. And oh, if you're wondering how to see the show if you're not a PlayStation owner, you should be able to watch online provided you're willing to pay for a PlayStation Plus subscription (which you can get free for 14 days if you just want to have a peek). Check out a preview for the series below.

Agents of S.H.I.E.L.D. (ABC) Tuesday, 9 p.m. - "Who You Really Are"

Lady Sif Alert! - Agents of S.H.I.E.L.D. has been relatively light on Marvel movie tie-ins, at least in terms of characters. We haven't seen any of the Avengers grace us with their presence on the show, but we have seen Nick Fury, Maria Hill and, perhaps most exciting of all, Lady Sif, Jaimie Alexander's Asgardian warrior, who steals scenes from right under Thor's nose if given the chance. Hopefully, her presence will provide a boost to the series, which, while it is experiencing more acclaim this season, isn't maintaining the viewer levels of season one at the moment. This week, Sif's suffering from memory loss after a battle, and Bobbi and Mac are still concealing their real mission. Check out a preview below.

Dig (USA) Thursday, 10 p.m. - "Catch You Later"

New series alert! - We didn't feature the pilot episode of Dig in TV This Week last week, but Blastr did have an exclusive interview with the show's creator, Gideon Graff, so you should definitely go check that out if you want to know what this series is all about and where its origins lie. Like some other series we like to mention here now and again, it's not strictly genre, but it does pack enough genre-adjacent interest that we thought we'd at least take a moment to mention it. It's the story of an FBI agent (Jason Isaacs) stationed in Jerusalem, who begins investigating the death of a young archaeologist and gets roped in a 2,000-year-old conspiracy. We don't yet know just how deep the conspiracy goes or where it's headed, but we do know the whole world could be at stake, and that makes this show's ambitions lofty enough to merit at least a mention among genre TV. It's got ancient cities, ancient conspiracies and secrets that go deep, and that's enough to make any Indiana Jones fan take at least a little interest. Check out the pilot on Hulu, and check out a preview for the series below. 

The Walking Dead (AMC) Sunday, 9 p.m. - "Spend"

With just three episodes to go before the season finale, we thought we'd take a moment and see how one of the biggest shows on TV is doing. For starters, it's still one of the biggest shows on TV, so that's good news, but there's an interesting little development in the show's ratings that I did want to unpack for a second. The tradition of the midseason finale and subsequent midseason premiere for this series began with season two, and at the time it aired the midseason finale of season two was the most-watched episode of the series ever, besting the previous record by nearly 1 million viewers. By season three the Live+Same Day midseason premiere audience grew from 8 million to 12 million, and last season the episode drew a whopping 15.76 million. After the record-breaking 17.89 million-viewer season premiere for season five, it seemed this year's midseason premiere was set for another high mark, but then ... that didn't happen. The audience was just slightly smaller than season four's midseason premiere. We've all been wondering since this show exploded just where its ceiling might be, and when we might see the point when The Walking Dead began to finally decline. So, is the midseason premiere a sign that the ceiling is here? No, I don't think so, and it's in part because of what's happened since. On March 1, the show posted 14.43 million live viewers, nearly 2 million viewers more than the episode that aired in the same week last year, and nearly 1 million viewers more than the best season four could do in the weeks between midseason premiere and season finale. Sure, the midseason break didn't produced quite the lift we might have come to expect from this show, but overall, the core audience is stronger than ever, and I'm expecting big numbers from the season finale. Besides, even if the show did start to dip, it's so far ahead of most other shows on TV, even the hits, that it could coast down a ratings hill for quite some time before ever being in trouble. The zombie apocalypse goes on! Check out a preview below.
