Look, we were all … ahem … burned by the finale to Game of Thrones.
With the world watching, and without a book from author George R R Martin to work from, showrunners David Benioff and D B Weiss delivered a finale that in retrospect, thoroughly whelmed the audience to the point that the show dropped out of the cultural zeitgeist faster than you could say "valar morghulis".
But while we were willing to forget about Westeros, HBO didn't want to let go of the show that became its most-watched ever during its eight-season run.
