i be puzzle by some of the review i have see . how many documentary be over before you know it and leave you want more . i find it pretty amaze what these kid be capable of as well a how this all seem to come together by accident . paul green teach his student with a great deal of passion and more importantly have the respect for both their ability and their potential ability . how many kid get to share the stage with actual rock icon . some people seem put off by the tough love thing that be part of the instruction but it seem to me that the only time he get impatient be when it be obvious that certain kid weren not try their hard . besides and you can not really argue with teach kid that they can get where they want to by work at it .
