I am completely addicted to this show. It is so good! I actually read the books years ago when I was living in Norway, but there hasn't been a new release in the series since then and so I mostly forgot about it. I was really skeptical about the show considering how cheap fantasy usually is on television (xena, sinbad +++), but wow! The show is carrying most of the qualities from the book series and then some. The actors are fantastic, the images are fantastic, the sets and costumes are fantastic.
For those of you not familiar, I really recommend this show. Even if you are not normally into fantasy it is definitely worth checking out. Where other series can get a bit hokus pokus and out there, Game of Thrones is very much rooted in reality. The characters are super interesting, with no one really being all good or all bad. Monsters and magic are present, but it is something very peripheric (sp?) and mysterious.
If you have read the books or watched the episodes feel free to express your enthusiasm in the comments, but please don't spoil any of the plot. There are a lot of twists and turns and to enjoy it fully you should know at least as possible.
