science fiction, fantasy? or thriller-horror-romance-chick-lit?

diceytillerman asks some questions about The Giver's ending and genre which very much mesh with my perpetual autumn concern these days, about definitions of science fiction and fantasy.

diceytillerman and I have spoken before about how my primary concern is trying to pin down generic markers despite the fact that my OTHER primary concern is my belief that it is absolutely impossible to pin down generic markers. Ultimately, I think that genre is one big ball of wibbly-wobbly timey-wimey goodness.

Ooo, I need a TARDIS. Or, I guess, a TARGIS (Tropes and Relative Genres in Space). Then I could travel around genre having adventures and writing wrongs along with my plucky companion (diceytillerman) and robot dog (any volunteers? I nominate steepholm!).

I wonder who my narrative archnemesis is?
