OK so some of us find it easy to believe that the writers really did find it too difficult to write for Kes and they put soo much effort in and they found it didn't work.
And some of us feel like Kes was easy to write for and the writers were just lying.
And some of us, like myself, feel like only some writers had issues writing for Kes because they were kinda lazy and couldn't be bothered thinking of how to write for a fairly unique character, while other writers such as Kenneth Biller were inspired by Kes but simply weren't high enough up the pecking order for his opinion to be taken seriously.
Let's just agree to disagree. Surely most of us can agree that Jeri Taylor wasn't particularly a fan of writing for Kes or she would have kept her on the show.
