The ‘Supergirl’ film struggled to connect with audiences, and behind-the-scenes turmoil contributed to its lackluster performance. Extensive script rewrites, added scenes requiring extra filming, and conflicts during the editing process reportedly reshaped the movie. These issues ultimately distorted the original vision for the film. Sources suggest a key factor in the film’s failure is declining interest in the superhero genre among Generation Z. This points to a potential shift in audience preferences, indicating that traditional superhero narratives may no longer resonate as strongly with younger viewers. The production difficulties and changing tastes combined to hinder the film's success at the box office.
