Annoying Dax was one of the worst things on tv that season! We agree on that! :-)
(Cute as a button, though. Especially when they knock over a casino. Cute chick)
I liked Jadzia Dax a lot, by the way - I found her attractive in a ballbusting way. Hahaha! DS9 was the last best Trek, but it's all relative: that's like saying it just didn't suck as bad as all the other TNG and beyond Treks.
Yeah Berman made a mistake when he didn't sign her for a seventh season. She wanted more money and Paramount wouldn't pay her.
TNG was getting boring at the end. To me Voyager was the worst Trek show and I think it killed the franchise.
