This documentary will be nominated for an Academy Award, so don’t miss it while it’s still around. It gives a good, touching picture of hard-working kids and parents, their impoverished surroundings, and their tension and suffering as they apply--against great odds--to schools offering prospects for graduation and even college. Geoffrey Canada, mover, shaker and advocate, is articulate and persuasive explaining graphics showing how badly America prepares its children compared to other countries, and how blithely ignorant of that fact we are. Message: Superman is not coming to save us so we'd better get busy.
It gives a pretty good picture of problems of getting rid of inferior teachers--which are increased by non-child centered practices of unions and bureaucracy.
It wastes chances to portray just what it is that good teachers do, how they do it, or how they should be taught, but the film should still be seen, though you may want to arm yourself with comfort food snacks.
