I have to admit that DS9 is probably my least favorite Star Trek series. While it did have some terrific characters and some captivating story arcs, there were too many "soap opera" episodes. I found myself frequently bored, taking stock of what I'm watching and half thinking to myself "do I abandon this, or keep watching?" Never happened to me in any other Star Trek series.
Still, DS9 is an essential part of the Star Trek universe. And as a captain, I think Avery Brooks did a terrific job. Very strong character. I truly like the way he evolved.
