Yes, the film is inspiring and evokes awe for the beautiful work depicted. But the film sets up classroom relationships based on care and love, opposed to expectations of learning, testing, and obedience. Little attention is given to the learning that is likely expected to be done. Further, from my experience inside CPS classrooms, as well as stories from other teachers, the behavioral issues depicted in the film are non-existent to mind-numbingly mild. If the classrooms in the film were intended to model how classrooms ought to be, I would fully agree. Unfortunately, the film ought to be watched as a piece of recruiting propaganda and public schooling fantasy.
For a different perspective on youth and school-life, though not focused on teachers, check out 'Chain Camera'. Also filmed in LA in 2001, this film has students taking a camera with them for a week each to record their lives. The stories of several students are edited to comprise this interesting portrayal of youth culture.
