Depending on how you see this, you will give it more or less latitude. It is a very good teenage movie. I'm not sure it tries to be more than that. It wouldn't be a great sci-fi film. The hand-held camera, documentary done by one of the characters style is not a plus. And there would be nothing wrong if the approach was simply Teenage Heroes, or Growing Up (pun intended). It has some nice moments. Fun enough, though.
