If you follow sports, you know that we've entered that magical season known as "March Madness" over in the college basketball world, so our TV schedule might look a little lighter than normal to make way for all the games. That doesn't mean we don't have big things on the way this week. First, there's the season-six return of Community on Yahoo! Screen, then the series premiere of iZombie over on The CW. Plus, The Walking Dead is rocketing toward its season finale, new PowersSupernatural returns on a new night, and Grimm is back.

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

Highlights of the Week

Community (Yahoo! Screen) Tuesday, Streaming - "Ladders" and "Lawnmower Maintenance and Postnatal Care"

Season premiere! - About 10 months ago, Community fans were crushed when NBC decided not to bring the show back for a sixth season, even after the show gained a bit of redemption in season five after the return of creator Dan Harmon. These days every time a show leaves before fans would like it to, everyone clings to the hope that a streaming service like Netflix could save the series, and Community was no different. Very often such fans are let down, but in this case Yahoo! Screen swooped in and picked up the series for a sixth season. We don't yet exactly what to expect, plot-wise, but we do know that the show will feature two new main cast members -- Paget Brewster and Keith David -- and will get to run a little longer than it did on broadcast TV. Unlike Netflix programming, the season won't drop all in one chunk. Instead, it'll hit weekly, starting with a two-episode premiere on Tuesday. Check out a preview for the season below, and get ready for more Greendale weirdness.

iZombie (CW) Tuesday, 9 p.m. - "Pilot"

Series premiere! - We've seen a lot of comic-book adaptations pop up during the 2014-2015 TV season, and we'll see more very soon, but none of them have quite the flavor of iZombie, the new series from Veronica Mars creator Rob Thomas, loosely adapted from the 28-issue Vertigo Comics series of the same name by writer Chris Roberson and artist Mike Allred. Both versions of the story star a young woman who is turned into a zombie and must periodically consume human brains in order to maintain her human appearance and intelligence. When the consumes these brains, some of the person's thoughts and memories are passed on to her, leading to all sorts of supernatural fun. In the comic book, she's a gravedigger, but in the TV series, Olivia "Liv" Moore (Rose McIver) is a medical resident who begins working at a coroner's office to get access to brains. She eats the brains, she gains some of the victim's memories, and as a result, she can help local police solve murders. Early trailers for the show feature a very Veronica Mars-ish vibe in terms of Liv's voiceover tone and sense of humor, with a little bit of Pushing Daisies style dark comedy to boot. Throw in some action, some supernatural intrigue, and of course some romance, and The CW could have its next genre hit. Check out a preview below.

Supernatural (CW) Wednesday, 9 p.m. - "The Things They Carried"

There's really not all that much to check in with when it comes to Supernatural. The show's moving right along through its 10th season, it's coming back for an 11th (which will means it surpasses Smallville as the longest-running CW series ever) next fall, and plenty of fans are still onboard. We're highlighting it this week for a couple of reasons, though: One, it's back after a month off, and two, it's moving from Tuesday to Wednesday now that iZombie's finally premiering and The 100 has wrapped up its second season. So iZombie moves to Supernatural's old Tuesday timeslot after The Flash, and Supernatural moves over to The 100's timeslot, after Arrow. This week, Sam and Dean team up with Cole to work on a new murder case. Check out a preview below.

12 Monkeys (Syfy) Friday, 9 p.m. - "Divine Move"

Fans of Syfy's new time travel-driven thriller got some very good news last week, when it was announced that the show will get a second season on the network. If you just glance at the show's Live+Same Day numbers, that might be a bit puzzling: The series premiered with 1.35 million Live+Same Day viewers, which isn't bad for a cable series on a Friday night, but isn't great either. It hasn't hit a Live+Same Day total above 1 million since January, though, and posted a series low of 0.66 million viewers in February. Like more and more series these days, though, DVR numbers are where it's at for 12 Monkeys. The show gets a massive Live+3 increase every single week, and according to Deadline the increase averages a whopping 104 percent of the live audience. People might not be staying home on Friday nights with this series, but they're very happy to record it and catch up over the weekend, and that's paid off both for 12 Monkeys and for Syfy. We'll see it again next year. This week, things come to a head when Ramse does whatever it takes to protect his newfound family.

The Last Man on Earth (FOX) Sunday, 9 p.m. - "Dunk the Skunk" and "Some Friggin' Fat Guy"

Now that The Last Man on Earth has a few episodes under its belt, we thought we'd check in and see how the show's holding up. At first glance, many (myself included) might have considered the series to be an inventive conceptual piece that would draw a core fanbase but potentially alienate more casual viewers. There was a chance a show like this could be just too weird for a lot of network viewers, and that it would eventually fade away. Well, it still has a chance to fade, but so far The Last Man on Earth is proving to be a success for Fox. After a strong premiere, the show's second week lagged a bit in Live+Same Day, but picked up a 3.0 DVR rating in the key 18-49 demographic, putting it ahead of perennial hit Family Guy and every other Fox comedy. The show also managed to best Once Upon a Time, which is usually the top scripted series on Sunday night broadcast TV. So far, viewers are sticking around, even if some of them are waiting a few days to catch up. We just have to see if that'll last. This week, the topic of reproduction and repopulation comes up again.
