They had no ship, and just sat on a space station.
Which meant that they had to face the consequences of their actions, something other Trek's didn't have to do by and large.
Sitting of the Station week after week was big turn off.
On the contrary, it was the show's biggest strength, esp early on before they started in with the conflict with the Dominion. Remaining in one place forced the writers to look to the characters and their circumstances for plot and drama as they didn't have the crutch of "planet of the [adjective] aliens of the week" to lean on.
That worked out so well for the series that by season 3 they added the Defiant to help out the serious flagging DS9 series.
Others have already addressed this.
DS9 was so awful it was the first & only Star Trek series that hired an actor from a previous series (Michael Dorn) to reprise their character role (Worf) as permanent cast member addition.
Wrong.
I was shocked that the writers felt that a Star Trek show didn’t need a real ship for exploration & wasn’t surprised that by season 3 they introduced the Defiant as a ship permanently assigned to Deep Space Nine (the runabout idea was a really seemed like someone’s idea of a bad joke since it really wasn’t designed for long range deep space exploration nor was it capable of real defense of the space station).
They did plenty of exploring even prior to the Defiant if you understand that Trek was NEVER about "planet of the week", but about using the Trek environment to explore the human condition. All of the interesting visuals and costumes and settings were minor elements designed to entertain the eye while the story fed the brain.
Which isn't to say that each and every ep was "deep thought" by any stretch of the imagination (then
or now). Sometimes they took a break and just had a little fun. Sometimes the story didn't turn out as well in execution as it may have looked on paper.
DS9 was just too painful to watch & Star Trek in name only.
Nope. It was probably the MOST faithful to the true spirit of Trek of all the modern serieses.
Voyager was the first series since the Original Series to really recap the Star Trek them of exploration of the unknown, and true sense of adventure
In a shallow, superficial way that was easily (and promptly) dismissed after each ep.
(I was hooked before the series premiere episode "Caretaker" had finished airing).
"Caretaker" had me going right up until the last few minutes when Janeway declared they would make it home as "one crew, a Starfleet crew". I knew right then that they would only pay lip service to many of the plot threads they had started to set up earlier.
The writers (thanks to studio and network meddling) had to turn their back on their own basic premises time after time (such as the overuse of the infamous "reset button".
What Voyager COULD have been was what we got with the Battlestar Galactica remake with some outside exploration thrown in for good measure.
What Voyager actually turned out to be was "TNG-lite", only with less cast chemistry.
