I've noticed that pretty much *every* Trek show has been unpopular in terms of ratings and/or amongst the fans in the original run, except for The Next Generation that ended strong as it gained more ratings, popularity and approval among Trek fans and the general public. It seems like all of the shows were unpopular in the beginning. The Original Series was an exception. It had a decent start, but people lost interest in it, en-mass, when it came down to it, eventually... even if it had a cult audience and was a write-in hit. Even though a lot of people nowadays, at least, consider Star Trek: Deep Space Nine to be the best Star Trek television show, I'm scratching my head to wonder if it encountered the same 'curse' that every other show of its kind encountered. The plot and characters were much more plot heavy and interesting as they went along according to what the fans say, generally speaking. It was the best show for thick plot and characters, but TOS is still my favorite. I could be wrong about this (but it is an opinion after all) that DS9 was a cult hit among the fans and writers who paid close attention to the whole of Star Trek and wasn't a fair weather/cursory fan (that may not be the right expressions, but I wanted to use a synonym in the sense of the word "casual" in that context) drawl to massive amounts of people. The reasoning for DS9 not being as much a hit from the beginning might also be three-fold: One, for instance, there is a general consensus amongst the fans that Deep Space Nine got better as it went along, with Season 1 being the worst and Season 7 being the best (which it ended on.) There was a little exploration in Season 1, but it slowly faded out (if not more so as it went along to its end.) Two people also didn't like the show because it changed the utopian ideals of Roddenberry for a more (some say more realistic) glitter Trek to tackle the darker side of life. That might have and still might turn people off, but the show is the best received among people who are not the more causal The Original Series and The Next Generation fans that seem to bring in the more general public than (I'm assuming) people like us who try to pay attention to everything that comes out for the fictional universe. Three, there was also no single channel that showed the show throughout its first run (according to Wikipedia... ) I was days before being born when Star Trek: Deep Space Nine came out... you could say I was a little preoccupied... ??!!!
