As we continue Rock and Roll month, it doesn't hurt to do a little homework for it. When Dewey is fired from his band and needs rent money, he decides to impersonate as his friend, a substitute teacher. Would should be a jail sentence provides an opportunity to teach kids about rock music and create a band for the tournament in a few weeks. This is a nostalgia film, so we're not going to sit here and pretend its great, but it does have a charismatic lead in Jack Black with a great soundtrack and some humor that still holds up. Rocking is fun, but "rocking ain't no walk in the park lady".
