I'm a huge fan of the series. I've been reading and re-reading over the last few years, and it's one of my personal favorite book series. The show is okay. It's enjoyable for me and approachable for people who will never touch the books, such as my wife. The show doesn't have a fraction of the back story, history, or depth that the books do, and that's okay with me. Lately, I've become more concerned that the HBO series will finish before the last books are published. It would be very disappointing to see how the show ends ASOIAF while missing all the depth and connected plot lines that the books cover. The show also has deviated from the plot lines recently, so there is that. I'm not sure how anyone who exclusively watches the show will pickup on the R + L = J, the Blackfyre pretenders, etc. that are likely to be critical plot components in the next two books.
