There is so many excellent great things to say about this film. To start off I will say it may be slow and to different for some to enjoy and so that I warn you. Now I will say that I can not express the idea enough of how surprising this film is. Jk Simmons does an outstanding performance as the highly unpredictable hair trigger tempered teacher Fletcher, Miles Teller an actor who I've only seen in mediocre comedies also shines in a breakthrough performance as the ambitious drummer Andrew. The performance are outstanding and that's just the tip of the iceberg.
