So I ask you, Niners, to convince me further.....
You either want to watch the show or you don't. If you don't give it another chance, the only person who misses out is you.
I feel this way pretty much also.
I mean, TNG's first couple of seasons are WAY worse than DS9's are, and if he likes that and got through it on the way to the better stuff, then there is no accounting for why he'd dislike DS9 by comparison and drop it so quickly. I mean,
Encounter at Farpoint is a godawful mess.

Give me
Emissary every TIME!
And DS9 improves - especially after the Dominion is introduced.
Like most people around here, I love it when new fans show up and gush about how they gave DS9 a try (or another try) and decided that they'd made a mistake to ignore it completely or give up on it so early...or that they were too young to appreciate it the first time but love it now...or whatever reason they give for their change of heart.
But I think people have to WANT to give it another try. Because if you go into it wanting to dislike it and insisting that fans 'convince' you that it is, in fact, worth watching...well, that is not really giving it a fair chance.
I don't really know where the OP is on this issue, or why he wants us to 'convince' him. But my feeling is that he should give the show another chance (a real chance - not just the pilot or whatever) and let IT convince him.
Of course, that is going to take some patience on his part, because DS9 is not immediately everything that it becomes later on. When I rank the seasons, in order, they end up like this:
Beyond Great:
6
7
Great:
5
Very good:
4
3
Pretty good, with the exception of a couple of duds:
2
Just okay, with a few very bright spots that give a glimpse of it's potential, and a couple of utter duds:
1
But of course, he can't start at the point the show gets fabulous, because part of the reason it's so good later on is because of all the character development that happens earlier, and all along. I mean, would
The Visitor be as good, for example, if you didn't really know Ben and Jake very well, but watched that episode out of the blue? I don't think so. The power of that episode is in the fact that we CARE about these characters by that point.
My feeling is that DS9 is like good Scotch - it takes a while to reach it's peak. So you have to be willing to wait - you have to have patience and stick with it.
If you can't do that, nothing we say in this forum is going to convince you.
