Lexx: Xev and Kai

I have been revisiting Lexx, and it occurs to me that the basic dynamic between Xev and Kai is one of the most poignantly realist doomed love stories I have seen in science fiction TV. To be sure, it's full of camp craziness on the surface: she's a half-lizard "love slave" with an "accelerated libido"; he's a dead guy with funny hair, etc. But if we read their various traits on an emotional (or metaphorical) level, the relationship that emerges is easily recognizable in the real world.
