I did my part.
They went out this morning.
Unfortunately several sources are saying that the fate of Kings is pretty definitively grim, but oh well. I gave them a piece of my mind anyway. It's a shame to lose this show. Not only is it great but I feel that it's actually a show that would be able to hold itself together for a few seasons because of the amount of source material it has to go on, unlike most other dramas that have a concept that bears out for a season or two at most and then starts falling apart.
