No.
I hate Jadzia Dax because:
1. She is horribly acted (one facial expression, monotone, wooden delivery of every line, etc.).
2. She is horribly written (not once did she ever say anything worth listening to; her 'jokes' were never funny; her "Curzon did this, Curzon did that statements" can cure insomnia because they are so unbelievably boring to listen to; every one of her lines was a waste of screen-time).
3. She is inherently annoying due to her smug, pompous attitude.
4. She serves no useful function on the show whatsoever; her character is therefore 100% irrelevant. That is why they didn't even bother to replace her with someone who performed the same function that she did (i.e. 'science officer'.) If she was not useless and irrelevant, they would have (yes, I know they cast Ezri, who also is useless and irrelevant to the show, but she did not replace Jadzia's function, because Jadzia had no function). It is
very obvious that Jadzia was cast for 'eye-candy' purposes only (even though she doesn't look good anyway, yet inexplicably some people think she does

)
5. Her rampant promiscuity does not make her 'cool' or whatever the writers were going for with that, rather it just makes her even worse and more of a joke as a character.
6. Disgustingly, she had the gall to insult a bonafide real-life literary master, Victor Hugo, for allegedly writing 'one dimensional female characters' even though she herself, Jadzia, is one of the very worst and most one-dimensional female characters ever written.
