argh yep we watched the full series back to back in less than a couple weeks which is a record for us.
I don't know if I want to read the books as the show was just amazing. Any thoughts on if I should take the plunge?
Yes I would definitely read at least the first book (which covers the same ground as the first season of the HBO show). I watched the show first and then read the book and I understood the show a lot better as a result. The HBO adaption was very well done and tracks the book closely. Plus the first book (in fact the first three books) is very good literature and well worth reading in its own right.
