I went with "hate", although my real feeling isn't that strong. I'll say this: I liked Terry Farrell as Dax up until I discovered that she had manuevered herself into a corner where she felt like she had to leave the show to save face due to a failed attempt to get a raise. Not bright. It was a bit of a betrayal of the role she was playing (when she had to know the show was coming to an end before long, anyway), and a bit of disregard for the fans.
Ezri was alright, but her introduction felt forced (which it was), and de Boer didn't have time to build the new character up very well. For both of those things, I also blame Farrell.
I don't hate her, though - it seems to me that her actions were due to a bit of general ignorance combined with the seemingly all-too-common feeling amongst Trek actors that "it's just a tv show" and acting on it is "just a gig." Not real outright hate or disrespect for the fans, like a couple of them that I can think of.
