I started Watching LOTS and I think it's an amazing show. Yeah so ok certain things don't match the book but you guys have to remember that the writer himself is working with them. Changes are going to happen because you can't follow what the book says on screen, people wont watch.
The producers and the directors and the writer/s have created stories based on the books. And they mention in the making of the series that it is based not copied from the books. Sometimes when you write a story then return to it you want to make changes. That's what writers do!
The Episodes so far have been brilliant, full of action and a plot which is missing in most shows now a days. The acting is brilliant and the soundtrack great. What more could you ask for. Even LOTR doesn't follow the book to a T and I haven't heard anyone complaining about it.
