The CW is less of a slave to ratings than the other broadcast networks but viewership numbers are still important. While the network hasn’t cancelled any of its live-action superhero shows yet, this season does mark the final chapter of Arrow so clearly, even hero tales have a limited shelf life. Could Supergirl be the next to go or, will it surpass Arrow’s eight year run? Will Supergirl be cancelled or renewed for season six? Stay tuned. *Status update below.

An action-adventure drama, Supergirl stars Melissa Benoist, Chyler Leigh, David Harewood, Katie McGrath, Jesse Rath, Nicole Maines, Julie Gonzolo, Azie Tesfai, Andrea Brooks, and Staz Nair. Based on the DC Comics character, the series centers on Kara Zor-El (Benoist), the cousin of Kal-El, i.e. Superman (Tyler Hoechlin). To remain safe from Krypton’s destruction, Kara grew up on Earth as a human named Kara Danvers. For years, she kept her powers a secret. Now, as an adult, she works at CatCo Worldwide Media and also for the Department of Extra-Normal Operations (DEO), a super-secret government organization whose mission is to keep National City – and the Earth – safe from sinister threats as costumed crusader Supergirl. In season five, National City becomes enthralled with addictive virtual reality technologies created by CatCo’s charming-but-secretive new owner, Andrea Rojas (Gonzalo). As Kara uses the power of the press to try to expose this danger, she must contend with challenges from rival reporter William Dey (Nair), renegade Martian Malefic J’onzz (LaMarr), a shadowy organization called Leviathan, and the shocking return of Lex Luthor (Jon Cryer) who, in addition to his plot for world domination, seeks to claim the soul of his sister Lena (McGrath) who is also Supergirl’s best friend.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly in the 18-49 demo), the better the chances for survival.
