There's just so many great Kes episodes, even if Jennifer was only in for a few minutes in a few, she always made the most of her few minutes. As Ethan Phillips said in the voyager time capsule Kes on the dvds "when she was acting you could smell the ozone". I was annoyed that in the last episode there was no mention or cameo for Kes, the only thing was a throaway line from Janeway about "let's remember all the people that can't be with us today" and there was only a little note at the end of the dvd timecapsules of Jennifer's name on the "Thanks To" List. The character had so much potential and was given the shaft. Before and after had some intriguing parts but perhaps wouldve been better as a two hour ep or two parter as there was a lot going on. I enjoy "Elogium" and "Warlord". The bit i like in "Fury" was the bit at the end with Kes and Neelix, it's not what was said it's what wasn't said, and then the moment was gone. I agree that "the gift" and "scorpion" were horribly rushed and contrived just to get Kes out.
It was a combo of Rick Berman never liking the character (glorified bean counter and ratings chaser, and what he actually created is open to interpretation, Paramount won't even let him on the lot now) and Brannon Braga's "excess" and chaotic writing eg "less isn't more, more is more". How impartial could he be when he was sleeping with Jeri Ryan? Not knocking Jeri because she is great and ran with an opportunity that was given to her as anyone else would. I think Braga put her in a bit of a bad position though. I would've loved to have sen a clash between Kes and Seven as they are opposite ends of the spectrum or have Kes as a recurring villian for a while that gets redeemed later. Sadly we can only speculate.
