We just saw the finale again for the first time in years and we made some observations I'm not sure we've made before.
To preface, I wanted to get the DVD so that I could watch the special features, and I watched a couple of them, including an interview where Ira Stephen Behr. In some parts he talks about how they gave all their characters as much closure and as much of an ending as possible so that whoever takes those characters on in the future has to deal with that (If there was a DS9 movie it would have to be sort of a "let's get the band together kind of thing, like TMP, TWOK, or Trek09. I think such a movie would have benefited from such a built-in premise as at least one of its threads).
He also talks about how all the couples are parting ways in the end. Kira and Odo, Sisko and Kasidy, Sisko and Jake, O'Brien and Bashir, Bashir and Garak, Odo and Quark, Quark and Rom (in fact Rom and Leeta are just about the only ones still together in the end--and they're on Ferenginar!). "This is heavy stuff!" Behr declared.
It got me thinking of another parallel: Sisko and Odo basically follow the same path: They find out they're at least demigods (in Odo's case his half-god status is cultural rather than genetic), they both go home to their people to teach them about what it's like to live with people who have solid and physical and complicated bodies that are incomprehensible to these gods.
And speaking of the Celestial Temple, my girlfriend observed "It's taken me twenty years to realize this, but that heartbeat is supposed to symbolize the womb." Obviously the producers didn't fully comprehend that. When they made "Emissary" they'd eventually give Sisko a prophet mother and it would make some kind of sense, whether they realized that or not.
Regarding the episode itself, it is kind of slowly paced, but engaging throughout. To some extent the finale was a little self-conscious of the fact that it was a finale, in a way that the Seinfeld finale tended to call attention to itself with lines like "Is this how it's really going to end??" But with DS9 it was much more of a confident victory lap than with Seinfeld.
At this point it'll be fun to continue following
DS9 on the AV Club, and maybe catching an episode now and again. But it'll probably be years before we watch it start to finish again. And then we can look at the story from beginning to middle to end. For that reason, it's still probably my favorite TV show of all time.
