I guess I'll be the lone voice the other way. I haven't read the books, but eventually will, and I DON'T think it's OK for the show to follow the books and then suddenly curve off to a completely different 'universe'. I was actually really disappointed that Peter Jackson added characters (unnecessarily) when bringing Tolkien's work to the screen. Similarly with those 'based on a true story' shows where story elements are inserted as necessary to fill gaps or make for a "better viewing experience". I mean, seriously, if you cannot just follow the 'script', you should instead be creating your own show from the beginning and leave already-established stories well enough alone. If I were GRRM, there's no way I'd assist HBO in competing with my creation like that.
