Well, if DS9 got better it lost a lot of loyal Star Trek fans in the process.
I stopped watching it after the second season. I didn't like any of the characters or the plot lines.
I watched it on and off for a while. It was the political tripe that finally lost me, though, it was the 'military'. I mean, good heavens, evil aliens spewing thru a wormhole, fleets massing, I expected heroism, maybe a major character or two playing Horatius at the cosmic bridge. What do I get? The magical wormhole dwellers tell everyone to take their toys and go home.
Deus ex machina. One of the worst cop outs in writing. Bleah.
