I have no issue w Ezri or how she was played. deBoer did a fine job. However, I was kind of surprised a new supporting character was introduced so late in the game with no hope of ever really developing her character. I think it might have been more advisable to let the Dax character die and concentrate on preestablished characters who could have benefited from more screen time, like Jake Sisko, Keiko (if they had made her more likable), Leeta or Garak. Also, the Breen were an intriguing but poorly developed race and the breathing room allowed by one less main cast character might have helped develop the Breen.
