Just watched this 2008 film, Surviving Summer, starring Hilary Duff. I was so into it. What a great film. Of course my viewing perspective was that of the father of the wayward know it all teenage girl. Totally got the viewpoint of the girl's grandmother, too.
The film should also work well seen from a teenage girl's viewpoint, a teenager's boyfriend's viewpoint, a mother's viewpoint, a mother's boyfriend viewpoint, a grandmother's viewpoint, AND a grandfather viewpoint ! Got it all, really.
