Here's a fantastic fan film that frames the story of Supergirl with the dignity that's so often been absent from her franchise. Read an interview with the film's star at Comic Book and Movie Reviews.
"Girl of Steel is a conceptual fan film based on DC Universe/Comics heroine, Supergirl. We wanted to produce a short story that empowers female role models. The Girl of Steel isn't just a superhero, but a freedom fighter inherited in all young women."
