Query: Great bio-pic

Kristen Stewart does an amazing job of transforming herself into Joan Jett here. She really looks and acts like Jett. Dakota Fanning makes a nice foil as the 15-year-old lead singer. No one remembers anyone from the Runaways except Joan Jett, but she is not given any face time at all in the extras. I wonder why? Cherie Curry appears, but no Joan. HHmmmm. I didn't really know the story behind the band, and this accurate bio-pic does a neat job putting it all together, showing southern California as it likely was back in 1975 when the teen band was put together. They look quite authentic when they perform, no mean feat. How many fake musical performances have we seen in similar movies by non-musician actors? Great job.
