I was never a fan, so I'd save "DS9" & butterfly "B5". Author's choice wins.
Well...
The thing is, the Trekverse is bigger than just the ships & exploration, which "DS9" (& DS9) could (should!) have shown in great detail.
There's room in the Trekverse, IMO, for shows like "ST:SI", as well as hospital ship shows, "Starfleet JAG", a UFP variant on "West Wing", and just about anything else on prime time TV IRL,
if the writers are prepared to take the challenge.
It's about perspective.
The "DS9" writers took a very narrow one. They blew a chance to do something
really different and do it
really well, with an exceptional cast perfectly suited for doing it.
Yeah, "DS9" was contrary to Gene's vision: it wasn't utopian (though there was the mandatory "everybody ends up friends" trope, which was a bit wearying). It
did allow the writers to explore a lot of issues, & IMO
that is what "Trek",
as a franchise, has always been about.
It could just as easily have dealt with a lot more. Like, are holograms people? (Does that make
Vic Fontaine a slave?
) How does the UFP economy actually operate? ("No cash", I expect, rather than the "no money" nonsense...) What are the actual requirements to qualify for UFP membership? (Did Bajor meet them? If not, why not, & which ones did it miss?) What are the ethics of experimental medical treatments? (Is Bashir violating patient rights by doing a surgery under Sisko's orders? {I'm thinking, here, of the EMH being ordered to operate on Torres, in
"Nothing Human".)
Worf's defense, when accused of murder for firing on a defenseless ship,
should have been handled by a station JAG officer, from an established JAG branch (to name just one case).
The writers sacrificed broad scope and real authenticity for simplicity and comfort...
