Very disappointing

Rating: 5/10 (26 April 2015)

The film isn't bad, but nowhere near what I had expected in a movie that won Sundance among many other things. Yes, JK Simmons is fantastic, but I want to know who the producer convinced that Simmons should have been nominated in the Best Supporting Actor category rather than Best Actor in this movie. He's in plenty of the picture. Of course, he couldn't have won Best Actor, but he'd be a shoo-in for Best Supporting Actor, which he won in spades.
Towards the middle and continuing to the end, the plot became ridiculous. Getting smacked by an oncoming truck where your car flips over, and then running to make your concert? Physically attacking your teacher? Going back to play drums for the instructor that you despise, and then how does he not know a certain song will be played, when everyone else does? Didn't he have to practice with them...like ever?
