This is a really great film and one of the best I’ve seen in a long time. It is intense and full of surprises. J.K. Simmons plays an uncompromising jazz band leader at a top music conservatory, and he comes off as a raging Drill Instructor from Hell – demanding complete perfection and even more. Don’t miss his performance, because there are going to be major award nominations for it. The student that he drives so hard is played by Miles Teller. And the music is great.
