Being a musician all my life and seeing this film makes me hate the main character. And more the teacher. He practices all wrong and he always has accuses. The best drummer doesn't made from playing fast, that is so stupid. The best drummer doesn't made from playing stiff, this is even more stupid. And the best music teacher surely doesn't made from a tough guy who do not the first thing how to teach, you can not push students like that to make great musicians. The whole point is to relax and feel the music. And swing is about feel the beat. You need to master the slow tempo so you can then be more accurate at higher tempo. What his film try to communicate about practicing and being the best musician is absurd. I stopped half way through the film, I just couldn't watch this non-sense anymore.

The main character does also looks very dumb as a person and worst as a musician and I believe not many musicians can relate to that. I wish this film deliver the right message about what being the real musician is all about. If you get that wrong then everything is wrong.
