I'll probably catch a lot of flak for it...
But honestly, if there was one character that DS9 could have existed entirely without, I'm sorry to say it... but it would be, in my humble opinion...
Agreed. I couldn't stand him on TNG, and especially not on DS9 after he and Jadzia got together to make the "Klingon/Trill Super-Duper Couple." It's a shame Terry Farrell didn't quit/get fired (not sure which) several seasons earlier. I liked Ezri.
