i'll give this episode points for actually giving some closure at the end of the series. the other star trek series seem to end very abruptly with a final explosive mission, and once its complete, that's it. sure, there might by some touchy-feely words at the end, but that's pertty much it.
then again, this episode was weak in its climax. i suppose i was hoping the pah-wraith's would make themselves known in the core of the final battle, but it seemed as though the writer's were simply throwing this in to tie up the path of the emissary. it could've done without the last 20 minutes, or tied the events into the first 40 much better.
the most touching part of this episode was listening to vic fontaine singing as ever character went through a series of flasbacks as they prepared to move on with their lives. that, tied in with the final scene with odo and kira, and then seeing jake watching the worm hole open and close tully did bring closure and an end to the series.
though the plot it weak, and events seem rushed in this finale, when you watch the final episode of Deep Space Nine, you'll feel as though you've just completed an extraordinary journey you were hardly aware you were apart of.
