First things first, it's very geeky. It's got kings and knights, crowns and swords, dragons and ghosts. Medieval drama is a genre we get precious little of on television (or in movies, for that matter), and Game of Thrones has nearly 10 hours of it. Plus, the series of books boasts fans who are as serious about the happenings in Westeros – where most of the book's action takes place – as any hardcore Trekkie or Star Wars geek is about those sagas.
