They eventually figured out what you could do with such a character, and then had two seasons of good Dax-stuff. But by then it was too late, because they've waited too long.
Bashir was a mess, but at least he had Garak.
Jadzia is the science girl… when she's finding wormholes or accidentally stranding the crew with their future descendants. She doesn't do much science, otherwise.
Every dude on the station was thirsty for her at some point. Even Captain Boday!
Everyone wants to fuck her. She totally fucked Morn.
But she doesn't want to fuck Julian! That's funny...funny as a hangnail.
At least she’s not constantly getting kidnapped by sex-slavers like Troi or Seven.
She’s the socialite, she can dance at Ferengi parties, Klingon parties… They tried pairing her with Kira a few times because they were the female leads, but Jadzia’s more of a “boys’ club” kind of gal, Kira is slightly more prejudiced so that wasn't much material there.
And then there’s Joran Dax. Oh no, not
another Hannibal Lecter whispering “
you’re a born killer”. She’s never shown a hint of murder tendencies. Who gives a shit? And he’s played by like three actors. I’m falling asleep just thinking about it. Can we get back to space and politics please?
I would have just killed him off in the first episode, reabsorbed him into Dax, move on. Enemies into friends, like
Star Trek usually does.
