For nearly a decade, “Game of Thrones” dominated television sets across the world, sparked a wave of Westerosi baby names and transformed on-screen storytelling.

The show’s massive fictional world featured dragons, White Walkers and magic; love, war and religion; and heroes, villains and everyone in between. As “GoT” turns 10 years old, Variety looked back to rank the seasons from good to greatest.
