"Half Nelson" isn't one of those "inspirational teacher/mentor" movies -- at least not in any generic or conventional sense. There's no triumph, no breakthrough, no by-the-numbers victory in test scores or on the basketball court. This movie isn't about those things, but is concerned with an even greater achievement that is generally unacknowledged: how people -- flawed, miserable, frustrated people -- go to work every day and find a way to care about something beyond themselves, despite themselves.
