I don't think most people got it. Obviously, the treatment of the 'livestock' humans was disturbing, and should be seen as such. The film replicated common practices exercised upon farm animals to humans instead, such as trapping in tiny cages, artificial insemination, milking, removing calves fron their mothers so as not to drink their mother's milk and killing them for veal, and killing heifers once they are no longer able to bear calves (and hence also to provide milk)--oh, and using knives as well as blunt objects to execute them. What should also be viewed as disturbing is that all of these cruelties are acted upon living, feeling creatures every day on actual farms.
