1) Put Kara Back At the Centre of the Show
The thing we most want to see in Supergirl season 3, above everything else in this list, is for Kara to be put back at the centre of her own show. As the series expanded in its sophomore year, the clear central character journey that Kara embarked upon throughout season 1 was lost. Though many episodes revolved around Supergirl learning some small lesson, it was hard to tell what her overarching story for the year was.
Certainly, the biggest character development this season was Mon-El, who Kara aided in growing from a privileged prince into a selfless hero. That was the key to the issue, though. Kara was an adjunct to Mon-El’s development, instead of him being an adjunct to her own. If you swap the genders, it’s like Iris West stealing the spotlight away from Barry Allen over on The Flash. It shouldn’t happen.
We love Supergirl because it’s sadly still one of the few places we can go to watch a female superhero’s adventures. If said female superhero isn’t even the star of her own show though, then you know something needs fixing. Let’s hope the writers realize this and sort it out for season 3.
