Yes, she should be brought back. Killing off major characters to boost sales is getting really tiresome; it's like a plague that's spreading.
As a TOS fan, I was really pissed off when they killed Kirk in "Generations".
Thank God for the Shatner-novels.
I'd like to see the reactions of the Picard- and Siskofans if they offed their precious captains; they would probably react exactly the same way as the Janewayfans.
The fact Janeway is winning all the "best captain" polls in General Trek must also be an indication it was a mistake.
And to clarify : no, I'm not especially a Janewayfan, but that character doesn't deserve to die.
If authors can only write a good story when it involves the death of a main character, then obviously they need to work on their imagination and creativity.
I can already find meaning in death in real life; I don't feel the need to find it in the death of a main character.
