I am truly enjoying the series so far, and the books are my favorite book series ever. I've read them one to 14 five times and starting again for a sixth. They are changing a few things but nothing major so far, and I love how they have interpreted characters and filled in gaps that aren't always filled in the books. They have not done anything yet that detracts from the story and done plenty to add to it. My wife has never read the books and she's more than hooked on the show and can't wait for new episodes each week.
