BTW, I feel like I've had the 'goal posts' moved on me much more than I've moved them myself in this discussion. The basic question of this thread has always been 'does a certain level of unrealism turn a story into speculative fiction at some point?' All the nitpicking about it possibly being sci-fi (because I used the term 'fantasy' instead of 'speculative fiction' to start) or 'crap writing' is pretty extraneous.

A 'yes, at some point it becomes speculative fiction (but not necessarily fantasy', if you felt the need to clear that up) or 'no, at no point does unrealism alone make a story anything' would have sufficed, especially for those whose other alternative seems to be getting enraged.
