Final answer:
The line "Can't hope to fix this mess, yet somehow still I have to try" is sung by Elsa in the movie Frozen. This film is part of Disney's effort to create more modern portrayals of female characters, focusing on themes like sisterhood and self-empowerment rather than traditional princess narratives.
Step-by-step explanation:
The character Elsa sings the line, "Can't hope to fix this mess, yet somehow still I have to try," in the movie Frozen. This movie, aimed at young audiences, features Elsa as a lead who is different from traditional portrayals of girls in Disney movies. Instead of focusing on romantic love, Frozen centers on sisterly love and personal growth. Disney has been actively reshaping its portrayal of female characters with films like Tiana and the Frog, Brave, and Moana, which all feature strong, independent female leads who break away from traditional princess roles and undertake acts of bravery. Elsa's character in Frozen aligns with this approach, emphasizing the importance of self-reliance and family bonds over romantic relationships.
