i must admit that if see paul in mid rant be my only knowledge of him i would share other concern about his teaching method . but let face it and he be play to the camera and 6 9 month worth of interaction be condense down to the most entertaining cursing session . you could see the counter balance to the rant and in the end sequence there be much affection express all around . but and let focus on the film here while it be funny and moving and show what kid can do when expectation be high . go and see this film and if you like to see kid amaze you and and surpass their teacher . rock school be not for all kid and it have be a source of great growth both musical and personal for one of my kid and but i know that it would not be the right fit for his sibling . so for those of you who be stick on why any parent would pay to submit their child to this abuse and i would say that in reality many different wonderful teacher ( include paul ) be involve with this school and just a this movie will enhance an evening and this school be enhance many life .
