Yes Glen, you should give DS9 another look.
It was only more or less limited to the space station, in the first 3 years. (I say "more or less" because in those first 3 years they did do a few missions of exploration in small ships called "Runabouts". )
But then, at the begining of the 4th year, DS9 exploded with lots of action and thoughtful, mind-blowing shows like TNG. That year, on the very first show, they brought on Worf, as DS9's tactacial officer, and the Federation went to war with the Klingon Empire.
Then, in year 5, the Federation and the Klingon Empire kissed and made up, and joined forces to repel the invasion by the Dominion.
And in years 5, 6, and 7, the great Dominion war was on, and it was a fight to the death, with the Federration, in order to survive, lying, cheating, stealing, and
even commiting genocide, in order to win.
In fact, DS9 is the ONLY Star Trek series that shows the "human" and "in-himan" sides of the Fedration. When "Section 31" of the Federation devlopes a germ to wipe out a whole race of people (
i.e. Genocide), you know that Star Trek has crossed a line never before crossed in it's 40 year history of being "nicey, nice".
It was shocking to watch the wholesome Federation and "good-guy" Star Fleet desend down to the lowest level in fighting the war. But that was the whole point of the show: To show what happens to good and decent people when they are forced to fight for their very lives. Nothing is "off the table" in this war with the Dominion, and the writers of Star Trek DS9 wanted to get away from that "good-guy" immage of the Federation, and show what war is: Hell, horror, death and destruction.
This is the very reason some trek fans did not like DS9. They loved TNG, and Captian Picard would never, ever lie, cheat, steal, murder, or condone genocide...... but Comander Sisko would, and did, in order to win the war.
Also, DS9, more then any other Star Trek show, has had more guest stars then anyone!
It's amazing how many different actors have been on DS9 as compaired to TNG or VOY.
Anyway, give DS9 anothe look Glen, you will be glad you did.
