We should be sensitive and emotionally sophisticated enough to recognize that the depiction of a mentally retarded man for comic relief is both infantile and demeaning. The film tries to take a scathing satirical look at ambition and the lengths people will go to win. While the filmmakers were not always successful, the topic is one that merits consideration. Jesus Christ's own disciples wrestled with ambition and competitiveness. Also a dispute arose among them as to which of them was considered to be greatest.
Competitiveness is a part of human nature.
But we know that human nature is controllable. Jesus taught his disciples that spiritual greatness requires humility, meekness and a willingness to serve. Qualities that he, himself, exemplified.
