I really love the novel A Game of Thrones. The detail is amazing, the characters have depth, the world is expansive. The graphic novel doesn't include any of the stuff that really makes me love the story. Of course it doesn't, it edits down a story that normally knocks on the door of 1000 pages (about 800 some for paperback).
I would recommend this for those who want to know what the story is but don't have the patience for reading a book that long or don't want to watch the TV series.
I'm sure more graphic novels will be made of the series but I'll give them the skip.
