Although this movie includes girls, and teenager girls, it is not a teen movie. IMDB classifies it with Comedy (well, some, but not that many), Crime (where?) and Drama. I just agree with this last one.
Also, the title is not appropriate for the movie. Main character might be a girl, and might be an american girl, but call the movie that? Imagine all police movies being called “American Police”.
Regarding the story, it is interesting. Nothing specacular… but kind of interesting… moralizing, maybe.
By the way, I’m not sure the image is from the right movie, as if it wasn’t for the title, I would say it is not. But IMDB says it is… so…
