I've really enjoyed it. Martin is an experienced writer, and it's just a joy to see a fully thought out and planned world. So many aren't more than sketches. Martin gives a sense of depth of field, if that makes sense. Be aware when you get to book 4 & 5: they're different. Book 4 is one set of characters and book 5 is another. The action takes place simultaneously until the end of book 5, when the two sets of characters come together in the story again. It was a difficult to get used to at first (and I've heard of plenty of people that drop the series at book 4), but it's ultimately very satisfying. I'm very much looking forward to book 6!
