I know exactly what you mean. ♥ I could go dig out a list of books & movies which achieve this, and probably will at some point. What makes speculative fiction so engaging for me is the fact that, since it isn't quite scifi or fantasy or reality, each work can create its own inherent logic and set its universe in individual clockwork-motion from there. And that completely new perspective can be so surprising, and so magical.

I shall be waiting for your speculative fiction film, dear. It'll become an indie-circuit cult thing, I just know it. :)
