The best aspect of GOT is undoubtedly the sheer depth of the characters involved. I feel like at least 5 individual characters could even branch off into their very own, unique storys/books/tv shows. They're that good.
If HBO stay faithful to the book for this series, then it will quite easily be the best series yet, the book is packed with action and twists and turns.
Fave GOT characters people?
Joeffrey!!!! - best villain ever
(No order) Varys and Baelish are the true players of the game of thrones how ever. I just love how crafty, intelligent and sly they both are.
