Everybody I know who has read the book and most on here that have seem to love both the book and the TV series and enjoy discussing the differences between them. It's not criticism of the series, some of the changes improve the story and some of the stuff left out needed to be, not knowing how they will interpret it keeps it interesting. There is no doubt the acting and production quality are fantastic, the settings, scenes, city's etc are supurb and the use of CGI has been perfect, not too over the top that it doesn't feel real. I've not been to Northern Ireland where it's filmed but it looks stunning. Can't wait until April for season 5.
