We had one of these on the old boards, and having just watched Season 2 of Game of Thrones I wanted another. Many things make the difference between a good and bad adaption. For some hard core fans, even minor differences can ruin a film, but I wouldn't go that far. Some adaptions, such as Harry Potter and the Prisoner of Azkahban are terrible, as the director seems to have no understanding of the material, and makes the decision to replace any dialogue that would explain what was happening and why with fart jokes and scenery. Others, such as Stardust can take immense liberties with the source Material, but still work well Clash of Kings Vs Game of Thrones Season 2 Spoiler I didn't think any of the storylines was better than the book, with the possible with the possible exception of moving Jaime/Brienne to season 2 from Season 3) The OK Jon and the Nightwatch This was pretty much intact, though Ygritte had a much larger role and I missed Quorin's line that he half expected Jon to release her and either way he would known more about what kind of person she was Tyrion Again, I don't recall any major changes, even less so that with Jon. Shae is still too clever and aware for it to be believable that Tyrion would fall for her, but at least they toned back the open cynicism. Tyrion giving Joffrey a whore and Joffrey getting off on having her beaten was actually a change I did like Dany. Major changes, but they needed to do something and having her spend half the series dying in the red waste would have been boring. I wasn't particularly bothered by the kidnapping of the Dragons, and the loss of the visions she received is understandable, especially as it seems they are really going with Ned as Jon's father (or at least have dropped all the hints from the books as to his true parentage) Arya It was a shame to drop all of Hoat, and to have her leave Harrenall without doing anything, as well as losing the freeing of the Frey/Bolton men, but I guess something had to go to fit the book in 10 episodes, and they seem to be trying to make her less harsh than in the books The Bad Theon While I can understand trying to humanise him, he still had two children killed so there wasn't really much point. Having Dagmer responsible for pretty much everything might have meant they would get away with not introducing Bolton's bastard, but his treachery was an important part of the book. Theon being stabbed at the end was just silly. If he hadn't won the loyalty of the men by that point, they could have left with his sister (whose TV name I forget) The Ugly Robb Again, he was barely in the book, so they needed to give him something to do, but to have him make a considered decision to betray his vows, rather than having him forced into it on a point of honour because of a moment's weakness is not good. It's going to be hard to have much sympathy for him at the Red Wedding, or to think of him as anything but an idiot for going.
