I honestly don't get the anger about spoilers from the show vs book; I mean, no matter what the book is going to be interesting just for the inner thoughts. And "big events", for me, are much more exciting on screen, in my opinion (I like books for information, but nothing beats a live action scene for exciting, again my opinion). I'd much rather have a book spoiled by a show, than the other way around.
But really, I'm just happy that no matter what, this story will end. Nothing worse than a series that doesn't get finished. Now, no matter what, I'll probably get to see the ending, one form or another.
