The 80s movie ruined cultural understanding of how great that book is, the concept of using religion versus enabling it, the concept of neo-feudalism arising from "Combine Honnete Ober Advancer Mercantiles" stock ownership, board meetings and silent partners, the concept of purposeful human breeding not on a massive scale but purposefully smaller scale, and as-you-say the concept of humanity's animal/man internal division rather than humanity itself being the division or progression past animal. Its rather sad that it doesn't get referenced more culturally.
