My thoughts on your thoughts! Agree with everything you pointed out, but...I just watch the show to be entertained, I try not to compare books to the show to much. I read the books before the show came out, and knew that the show would be "based loosley on the books". Have you ever read a book and than the movie came out and you were disappointed? At least with True Blood you aren't really disappointed, you just notice the differences, but it's still entertaining.
That being said, I hated the whole Mary Ann/maenad thing. It just went on & on & on! It consumed the entire season. That was one storyline where I wished they had just stuck to the book. But then with Lafayette, he wasn't that big in the book, but was a pretty central character on the show, and I loved him. Eric is great in the books, but I like his character on the show too.
Now that you have all the books & I am sure you are reading through them at a record pace..just enjoy the show & the books!
Looking forward to June and the new season!!
