Re: Why was Kes written off the show?
She wasn't "written into a corner," she had some of the best potential of any of the characters. If they were going to keep her around, they simply wouldn't have "powered her up" to the levels of "The Gift."
Those with actual power behind the show disagree.
That that solid fact trumps any opinions we may have.
