So long as we're clear that we're talking about your imagination, not an objective assessment of science fiction as a genre, we're all good.

You have to worry about the world-building. You need to build enough of a universe where aliens have been bred to relish their role as prey for a hunting species for the audience to accept it and confront the implications thereof. You? You get wrapped around the axle on O'Brien the military man who Would Never Do That (perhaps that's part of the world they're building...). You also come into this with a hell of a detriment: nobody watched DS9 without having been sheep-dipped in two series of Star Trek before hand. There is literally no one on the planet except you who said "you know what? I think I'll ignore the two series that the nerds actually like and focus on the one in the universe that people think is ehh at best before moving on to Voyager, the series most people hate so I can talk about how much sci fi sucks."

There are great swaths of TNG that suck. There are many episodes of the original Star Trek that fans would rather forget. But DS9 will always be "another series in the Star Trek Universe" that completists watch and nobody else cares about. If you really wanna get your dork on, go sit through The Animated Series and try and wrap canon around that. The Federation vs. Kzin. "Any script in a storm."
