I didn't read the books so what I see in the episodes are completely new to me. This series is outstanding, the plot it very complex, you get a lot of action/drama scenes. Sometimes it gives you the felling that you're watching a football match where you don't have a favorite team, but as the game goes you get this occurred felling and you get yourself backing a team as if they where your favorites from the beginning. It definitely makes you want more.
What makes this series so great is that you never know what will happen. In some series/movies you know XXX is the good guy and they will never die. They will always win. It takes out the suspense. Instead of wondering if your guy will win, you just watch to see how they will when. In this serie everything goes. No one is safe or secure. It is one of the first series where no one ( except those who have read the books) knows what will happen. (next phrase has a spoiler)For example, we have Ed Stark at the beginning. He is the guy featured on the posters. He is the King's hand. At the end of the 1st season, he dies.
I am loving this serie and sad I have to wait for Season 2.
