True
1. Tasha Yar - Bad Character
2. Jadzia Dax - Actress Left
3. Kes - Wasn't working, writers failed to develop her
But...
1. Yar came back in Yesterday's Enterprise and ended up having a daughter who looked like her with pointy ears
2. Dax came back via symbiote
3. Kes came back, tried to destroy Voyager
ST is reluctant to even completely kill a main character.
2. The series will run 7 years.
I think Enterprise has a good chance of breaking this tradition. It just won't be good for them
3. The series concept will remain consistant for that whole 7 years.
A little
1. ST:TNG - Remained consistant
2. ST-DS9 - IMO, the first two or three seasons are pretty different than the rest of the series
3. Voyager - First half: "How can we find a way home with all these strange new aliens we meet and the Kazon hounding us"
Second half: "Crap the Borg" little later "Future Borg" little later "The Raven, Borg Research Ship" little later "Borg-Children"
then Borg, Borg, Borg, Borg all the way to the last episode. I like the Borg, just not in every episode.
