The whole argument just strikes me as sad. Because this isn't about how good or bad the books are, it's not about the sucky way that Janeway was killed off (which was naff), it's about the fact she's gone, pure and simple.
Janeway could have survived Before Dishonour and Destiny could have been an epic Janeway-centric trilogy, brilliantly written, perfectly characterised, with Janeway dying in a blaze of glory and finally defeating the Borg once and for all, doing her character great justice and bringing her story to a natural end.
We could have had all that, and you guys would still be boycotting the new books because "they killed Janeway," quality of the actual books be damned.
Whereas if they left her alive, behind an Admiral's desk, with a few scenes in each novel, you'd have kept buying them. Moaned a bit about her not getting enough screen-time but you'd be buying the books.
And that's why this is sad. It's a binary state. Stories with alive-Janeway = good, stories with dead-Janeway = bad. Utterly regardless of how good (or not) the plots, characterization and such are. And that's also why this discussion is pointless. You won't buy the books again unless she's brought back to life. Okay, we get it. She's your favourite character, you're upset, end of. That's a valid stance to hold, but it's a personal, emotional one. There's no logic to it and it's not one we can debate.
