The Complex Story
What's unique about this show is that it doesn't have a definite protagonist. Rather, it has a lot (I mean, a lot) of characters that are all battling for the Iron Throne, where the supposed ruler of the Seven Kingdoms of Westeros (the fictional setting of the show) should sit. There is, obviously, no determined ruler; though many of the characters would disagree and try to stake their claim on the throne, which drives the story along. There's a lot of war and killing and political issues delved into within the story, which is presented from a different perspective given the medieval setting.
I know that you're probably thinking that since this is a medieval show, it's boring. Trust me, it isn't. Each episode will keep you on the edge of your seat, and will leave you wanting more. The plot is filled with many shocking WTF?! moments that will definitely keep you interested, especially if you haven't read the series.
