re: IsnDeep Space 9 worth the watch?

I actually just finished a re-watch of it. It's probably my favorite of the three "next generation" series. It's not like the other Treks, as it is more serialized than the others especially towards the final season. (There aren't a lot of the one-off episodes that don't connect to others.) Also, it doesn't show the future as some utopia where everyone, for the most part, gets along. The Federation is at war for much of the series.

But this makes for excellent character development. Garak, Dukat, and (over a briefer period) Dumar are all great characters. Quark and Odo's "friendship" is portrayed well in my opinion, and Quark develops nicely too.

It explores science, faith, duty, and politics pretty well. One of the better episodes actually goes back to the Tribble episode of the Original Series.
