Re: Game of Thrones (book/show) newbie (please no spoilers!)
Season 1 is very, very faithful. The only change that angers me is the lack of The Hound's big scene.
Seasons 2 and 3 are way less faithful and remind me of Peter Jackson's The Two Towers in how needless a lot of the changes/diversions seem to be.
Season 3 is a lot more faithful to the book than season 2 was. Most of the characters end up in the right places, and in some cases entire scenes are lifted straight from the page, dialogue and all.
