And then there are the students, who mostly rush past the screen in small crowds, gossiping and giggling. A few take shape more solidly: a young dyslexic boy who sometimes acts the fool because he fears he's not noticed at all, a girl with a checkered school record, a sad-eyed girl whom it seems no one can reach. We're almost at the movie's end before we hear her say a word -- but she gets there. She smiles! And so do we. It's a small happening, in a small and quiet movie. But in its own unassuming way, these people, and this movie, will get to you.
