Looks like we'll finally get a more mature Kara/Linda from DCTV and hopefully she won't be a teenager like the comics. Hopefully her cameo in Flash allows her to be shown in a future Superman/Supergirl movie— Roger (@Butters360) February 19, 2021The decision to defy the conventional portrayal of a blue-eyed, blonde-haired Supergirl has been lauded on the grounds of representation and diversity.As a result, initial fan reaction towards Sasha Calle appears to be positive, with her work in The Young and Restless seemingly reassuring fans of her credentials.With the DCEU officially getting it's very own Kara Zoe-El/Kara Danvers, all eyes are now on Sasha Calle, who has officially entered the big leagues.
