This probably contains spoilers, but I don’t know how much that matters with a movie of this nature.
‘Expelled’ does what it sets out to do, that is, it raises awareness of the ‘blackballing’ of ID from the scientific community. While Ben Stein’s own worldview does come through in his treatment of Darwinism, it is not the center of the movie. The theme of the movie is that of Darwin’s detractors being ‘expelled’ from any forum in which some very important questions could be posed to Darwinian theory.
Ben Stein argues that the proponents of ID deserve a place at the table of Science based not upon the validity of their arguments, although he does not discount their arguments, but on the grounds of ‘Freedom of Inquiry’, which is one of the traits that has made our nation great.
He also points out the fact that while Evolutionists cite crystals, or aliens as the source of life on earth, they regard the theory of a ‘designer’ to be ridiculous. But it is not simply the issue of a ‘designer’, as the alien theory suggests, since the alien would have been a ‘designer’ of life, but ‘who’ the designer would turn out to be.
The film is also disturbing as it shows the implications of a world based on Darwinian theory as found in history.
So, without giving away a whole lot of the movie, let me simply say that the movie is worth seeing, even if only from a ‘Freedom of Inquiry’ veiwpoint.
