littlelamb told me someone involved in the show got fired because he said they were making up the plot as they went along.

I did wonder if it's a story they know from start to finish, or if they have some motifs but are generally unsure where it's going. I don't know if it can go for 8 seasons though...

3rd season will only be arriving here next year, I think. Are you enjoying the 3rd season so far?
