I've been trying so hard to hang on to my firm belief that TNG will always be the best of the series after growing up watching it. I came here and saw that most people seem to think DS9 is better and still stubbornly stuck to my opinion, but it's getting harder now. I'm leaning towards the "DS9 is the best of them all" bandwagon now after seeing "Take Me Out to the Holosuite". I know, not exactly they episode you'd expect would push someone's DS9 fandom over-the-top, but what occurred to me when watching it is just how diverse the stories of this series are compared to TNG and especially compared to "Star Trek", which (as the people behind the show themselves have admitted) tended to stick to certain formulas (i.e. crew lands on weird planet, some supernatural being or beings invades the ship, etc.).
Now after seeing this episode and "His Way", I am just so blown away by how DS9 can do stories that are so beyond anything ever done on any previous Star Trek series and yet at the same time maintain the message of friendship/camaraderie/love, honesty, optimism, thoughtfulness, and thirst for knowledge being the human qualities that will allow the species to endure in the future against all adversity.
Watching these episodes is jarring at first. I think to myself how weird it is to see a show that can convincingly immerse you in a completely believable world of 50s jazz lounges or American major league baseball and yet still feel like Star Trek. The show takes chances that the others never dared and somehow maintains the hopeful spirit of Star Trek. It mixes that with things that should not gel with it on paper and succeeds because the direction, writing, and acting are so strong.
It may have its share of boring, overly chattery episodes (mostly the ones that deal with politics and religion, in my opinion), but it's taken Star Trek to creative heights I've never seen the other shows reach and even in the last season I'm respecting and appreciating it more and more as it continues to keep surprising me.
