This is not an entertaining movie. In fact it is a disturbing movie. It is a movie that makes you think; a movie that forces discussion; a movie that might even make you want to write an essay.
Though nominally about the conflict between Darwinists and Creationists the actual subject is much darker. It is about the rejection of the Enlightenment by those who would substitute enforced adherence to orthodoxy for critical thinking and Reason, and do so in the name of science.
Science involves skepticism about the common wisdom. It is about asking questions and testing hypotheses. You posit a theory and invite everyone to try and knock it down. That's the essence of the Scientific Method.
Increasingly, however, we are being told that we cannot question the scientific "consensus." Consensus is about politics not science. Science is about the freedom to explore, to ask questions and not to accept an answer simply because it is held by a certain number of influential people.
What Ben Stein is actually examining in his inquiry into why some scientists have had their careers destroyed for questioning the prevailing orthodoxy is not whether the universe created itself out of nothing, or if there is an underlying intelligence. Rather he is raising a red flag to the erosion of individual freedom as we are faced with a growing list of things we can't do, can't talk about and are not allowed to even think about.
