Honestly, there's so much I'd like to see that's different. Like yeah, Stannis is still very much alive in the books. We don't know if he even has an end or not in the story. So I'm a bit excited to see what they do with everyone.
The show is its own thing, I mean it has been from the beginning. So I kinda hate being like "but in the books!" cause they only ever have been more loose in their comparisons. Like the whole Catelyn arc. Hell just the general lack of Wolves and warging the show has. They're really their own thing so I don't like being like "but this one point in the books said XYZ" cause they said xyz a lot and we are way past xyz
