re: "this is science fiction"
It sure as hell is ... and some of us take it seriously, especially the ones who carry the tradition that science fiction should, first and formost, be grounded in science. We intensely dislike deus ex superior-tech machina. It's a cheap way out.
We also appreciate a well-told story, regardless of the genre -- which is another way of saying that we don't accept anything but the best from our own genre. So please, on behalf of those of us who not only enjoy it, but are ourselves writers thereof -- don't be so dismissive.
Because that's exactly what you were doing: "It's only science fiction."
