Nicole de Boer did a great job as Ezri and the writers did what they could with her character, but she always felt shoehorned into the show. The fact that her character intentionally didn’t fit in did not help at all. I guess they wanted her to be the opposite of Jadzia? And I really didn’t like the idea of the Dax symbiont put into the closest available Trill because it was an emergency plot device.
