You pretty much summed it up. This new TV series is aimed more towards the people who loved the books but we're disappointed by the movies. The first 3 seasons though are probably going to be pretty similar to the movies because the first 3 books were pretty short And the movies did a decent job of following them. However, the 4th movie was where they really veered away from the books in a lot of ways. Its basically the equivalent of someone remaking The Hobbit, since there's a lot of Lord of The Rings fans that hated The Hobbit movies because they added a bunch of random shit to them that weren't in the book.
