Don't pay too much attention to my Top Four. I don't even have a single favorite film.
Not necessarily aesthetically great or interesting, but narratively it's a really good story about the amount of dedication and effort required to become a great artist. It's a bit idealistic about the process maybe, but I don't consider that to be a problem. It's the rare film that tries to be inspirational and actual manages to do so (whether or not the attempt at inspiring is sincere or commercial on their part).
The 'severe teacher/driven student' plot may be considered…
