Really, there's no way to say this in a medium such as this without sounding like a douche, so please try to understand that I in no way mean it that way, but until you've actually worked on a show, --and I mean, not just a day or two, but a whole season of being there and bleeding and sweating and staying late at night and being a part of the process -the entire process -- then you really can't understand the whole picture of it.
I don't know what other way to explain it, but there it is.
Another element we have not yet considered: Those of you who constantly whinge and complain on this issue -- about all these stories that were left to tell about Kes... let's hear them. Because clearly, you believe those stories are there, and it would not be that illogical an assumption that you have at least ONE story worked out, so I'd like to read them. Prove your point to me and wow me with your never-told Kes stories.
