HBO's Emmy-winning mega-blockbuster adaptation of George R.R. Martin's epic fantasy concludes tonight as the battle for the Iron Throne of Westeros reaches its climax. Season 8 has proven to be perhaps the most polarizing in the history of this series, as one long-held fan theory after another crumbles and a mid-season combat-heavy episode left viewers open-mouthed with shock, not entirely for good reasons. Still, "Game of Thrones" has earned a permanent place in television history, and we probably won't see its like again anytime soon. Kit Harington, Emilia Clarke, Peter Dinklage, Sophie Turner and Maisie Williams star.
