While Kara Zor-El's appearance at the end of Superman was a pleasant surprise, Warner Bros. Discovery’s push for standalone films featuring other Kryptonians feels premature. Despite director Craig Gillespie and writer Ana Nogueira's efforts, Supergirl struggles to differentiate itself from its cousin, with familiar Guardians of the Galaxy elements and a plot that lacks intrigue.

The film's reliance on clichés and its failure to explore Kara’s emotions in depth undermines any attempt to build a unique universe. Critics and audiences have been unimpressed both critically and financially, with projections suggesting a loss of up to $120 million for Warner Bros. Discovery.

Warner Bros. Discovery's decision to prioritize Green Lanterns and Clayface over more established heroes like Batman raises questions about the studio’s strategy. With Marvel on the brink of its own major reboot, DC seems to be starting from scratch, potentially leaving it at a competitive disadvantage.

The close timing of Supergirl and Superman’s theatrical debuts only highlights their similarities, suggesting a lack of cohesive vision for the new universe. As Gunn’s grand plan faces early setbacks, it remains to be seen whether DC can regain its footing in the superhero landscape.
