||Without meaning to be sexist, this is the kind of episode that is normally written by a woman! There are a few episodes of Merlin which also feature doomed romances, again all by female writers, none of them interesting or dramatic. This doesn't imply criticism of female writers, simply that some genres don't combine very well. You don't get people submitting spy dramas to Take A Break magazine, after all! DS9 is not a particularly romantic show, no Trek is, so I don't see why people need to keep rolling out the cliched romance plot lines and call it science fiction.
