Thanks for the welcome
I am hoping to stick around and have recently been rewatching Voyager, so expect me to pop up on that sub forum too! I like all the different Star Trek series and films as well.
Kai Winn - I disliked her too. I didn't like her devious nature which she explained away as 'the will of the prophets'. I found it quite fitting how she ended up with Dukat in the end. It was what she deserved...
Ezri - I agree. If they were going to bring Dax back, then a change would have been much better, instead of Esri (a shadow of the Dax that had been before). A male Dax would have at least allowed a bit more expansion of the Dax character (and of course allow some funny interactions with Worf!).
