It seems to me that The Book of Eli, with its underlying religious themes, makes a good example of various Satanic perspectives. It shows the strengths of an egotistical and survivalist philosophy, and highlights various criticisms of the Christian religion that are exhibited in Satanism. While the movie obviously isn’t written with the Church of Satan in mind, and could be interpreted as an example of other religious philosophies, I think that it still shows the strengths of Satanism, as well as the pitfalls that it finds in other faiths.
Warning, hither be spoilers.
