I know that baffles you, but if people feel that way about DS9, how about doing something that Trek is supposed to teach us, and respect how others feel about it?
I respect the fact that you feel this way about DS9, no worries. But let others just like it the way they do.
The original poster asked what episodes might hook them on the show, not for DS9 fans to come tell them it's the gem of Trek. DS9 fans have this overwhelming urge to come rushing to tell people why their series is the best even when the thread has nothing to do with it.
I would get just as annoyed if it was a thread by a poster wanting to know what episodes of TOS might interest them and was then subjected to post after post of "OMG!!! TOS is the best!!!"
