I wouldn't want to live on a steady diet of dystopian fiction, or anything, but I DO usually find it more interesting than its utopian or meh-topian siblings.
I mean lets face it, dystopia usually goes hand-in-hand with post-apoc. And "good times" after an apocalypse seem rather unlikely, disingenuous, or both.
Still ... some of my favorite dystopian stories were ones where the dystopian society came not after "a fall," but rather because of societal trends.
I could see growing weary of the post-apoc theme (though I don't seem to tire of it myself if well-written), it's a fairly cut & paste path to the dystopian portion of the show that many authors seem to take.
