The writers are writing human beings, and they're writing about the human condition and how difficult it is to function in that condition. I think it's one of the charms of the show, the idea of redemption and working towards becoming better people, for everybody involved.
I have learned so much from working with other poets, travelling and reading with them, spending days discussing poems in progress. There is the sense that we are all, as writers, part of something which is more powerful than any of us.
Science fiction writers, I am sorry to say, really do not know anything. We can't talk about science, because our knowledge of it is limited and unofficial, and usually our fiction is dreadful.
Writers are not always right however, but then again, I've been on shows where the actors have complete control and change everything and it's terrible.
