A Supergirl TV show is coming, and while the smart place for the series about Superman’s cousin would be the CW, where Smallville lived on for a decade, it will air on CBS. This probably means that it will last one season and then get cancelled. Especially since the time slot it has earned will put it in direct competition with another DC Comics property.

IGN reported on Wednesday that Supergirl will air starting in November on Monday night’s at 8 p.m. EST and face off with FOX’s Gotham. This makes no sense at all. I understand that rival television networks want to compete with each other for viewers, but why would DC allow two of their own properties to eat each other?

It is one thing to have DC’s Flash compete head-to-head with ABC’s Marvel’s Agents of S.H.I.E.L.D., because Marvel and DC are competitors. It also doesn’t hurt much since Disney owns ABC and Marvel’s Agents of S.H.I.E.L.D. plays a role in the Marvel Universe, so Flash beating it in the ratings isn’t that big of a deal.

However, the only way that DC Comics fans can see both Gotham and Supergirl is through a DVR, and that doesn’t mean anything to ratings because DVR watchers skip commercials, so one of these shows will probably get cancelled, if not both, because they will eat each other’s audience live, when the advertisers with the money actually matter.

With that said, along with the time slot news, here is the synopsis.

Supergirl is an action-adventure drama based on the DC Comics character Kara Zor-El (Melissa Benoist), Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant (Calista Flockhart), who just hired the Daily Planet’s former photographer, James Olsen (Mehcad Brooks), as her new art director. However, Kara’s days of keeping her talents a secret are over when Hank Henshaw (David Harewood), head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime.
