The point made by the film is that the philosophical/ethical ramifications of evolutionary theory was Hitler's rationale for the Holocaust.
Which is demonstrably false and a very low blow. I believe it is an attempt to generate hatred (yes its a strong word, but Hitler was an incredibly despicable man) by making a false association.
There are no particular ethical ramifications of evolutionary theory. Most scientists are motivated by wanting to help others and many are very strong advocates of human rights.
Hitler's rationale was hatred and prejudice. Hatred and prejudice are bad, and are not the result of evolutionary theory, but have been around much much longer. Some church folk have contributed more hatred and prejudice in the world; some work against it.
I haven't seen the movie either but know that this premise is wrong. I would actually love to see it if I could do so without paying to do so, but I have no intention of making these hate-filled lie peddlers any richer so they can peddle more lies and inflame more hate.
