Haha, I'm one of those people that watches the show, but doesn't read the books. I do that with so much really.

The way I've heard about it though reminds me a bit of the Lord of the Rings trilogy as far as writing style (long descriptions and stuff).
I end up hearing about a few differences of note for some people and I've sided with the books in some cases, but overall I enjoy having the books and shows works as separate entities in a way.

I probably won't read them as watching the show is brutal enough.
