No, it's not. It's all about creating a good life for oneself.Stay where you feel good =/= career or money. That's absurdity on its face.
Why?False equivalency.
Definitely not. On the contrary, this is what most fans like, to have more good stories with their favorites.And it fails.
Just look at NCIS where Gibbs was the leading field agent for 19 seasons and people loved it. When the actor retired, the interest for the series sunk. It's not as popular as it used to be.
I watched every episode of the series up to season 19, now i only watch it occasionaly and it is the only TV series which i still watch.
Personally I've had some trouble with the "Relaunch books" too because the authors removed many great characters and added new ones instead. When I read a DS9 book, I want to read about Sisko, Odo, Kira and the others. Not seeeing Sisko be replaced by some Ebenezer Springerkoff as the captain on the station. OK, I can accept characters like Ebenezer Springerkoff and Miranda Whottley as characters in a story, like Broik or Morn but I don't want such characters to replace the original ones.
The same when it comes to Voyager books and stories. Having Janeway behind a desk, thinking about if she's gonna become a recluse on Ireland or start an ostrich farm is horrible.
