This is a well-deserved Oscar and, more importantly, one that I can understand.
Maybe a bit too long at times and, personally, I think the disciplinary hearing was too much. That speach about what's wrong with the school, the system, about punishing a young man for not selling out - althought well played - it felt to much of an urge to sell a morale. It did not fit in with the rest of the story. But overall well worth watching.
