I found Elantris to be interesting. It seems to fall as much in the political thriller genre as it does in the sci-fi/fantasy realm. It was interesting, but there was only a hint of the fantasy side. I do hope that the fantasy aspect of the book blooms much more in the following books. I am really hoping to see Raoden unlock the magic that is hinted at in the first book.
From a production stand point though, I wonder if GA shot themselves in the foot. This first book, as noted by the previous poster, is mostly setup of what's to come. As such, it really does feel somewhat plodding and when the end of the first book came, I really questioned whether to cut my loses on this series. I decided to stick with it, but it was a close call, and I don't often drop books.
