That Jack Black is a really nice fellow - watching a comedy featuring him doesn`t mean that you will spend something like two hours of your worthy (or less worthy) life watching jokes of the banana peel slipping category. I gotta admit that I tend to like films about rock music, even the most stupid ones (like `Little Nicky` where the heavy metal business saved the day for me). And this one ain`t that bad, it`s certainly not even in the quality of `High Fidelity` but it`s still pretty good, and those children that actually play their instruments - now they are really awesome.
