Jadzia... wasn't terrible, but really wasn't very interesting. Sure she's beautiful though, but her character had no... consistency. One episode she's the aloof smart person, the next she's drinking with Quark playing cards, the next she's killing people with Klingons. I mean... I get she's had seven different lifetimes and that would be pulling her in multiple directions... except she throws it in the audience's face quite often how she's Jadzia and not Curzon or the past Dax's and every joined Trill is supposed to define themselves from the rest.... we never really see that with Jadzia.
