For fans of Game Of Thrones, today is a day of mourning.
Not only is the show gone, but also the lunch-time arguments with friends and office buddies ("This season is awful!", "No, it was all foreshadowed!"), the theories posted on Reddit and fan forums, the geeky YouTube breakdowns ("Could Arya be the real Prince That Was Promised?") and the rash of Thrones-related podcasts that have sprung up.
