I just watched the new episode tonight... I think it's going to be a good season. Definitely one of the more entertaining shows, I haven't read the books but sometimes the story line bothers me a bit..
I am guessing that's what would happen to me.
My wife bought the DVD's of all the seasons. We watched the whole thing when she first got them and just got done watching them all a 2nd time last week. It was very good, but I didn't read the books so not sure how well they represented them. I quit subscribing to HBO years ago so never got into it.
