The book is okay, however for being a "Visual Exploration", there is no where near enough visuals. The text information isn't too in depth, but it was nice to get a few extra details such as the names of other Na'vi clans, flora and fauna that we haven't been able to see much of or at all. With that being said, I expected the text to be as brief as it is, but to also then be accompanied by a lot more photos. It is limited to one of each thing, maybe two if it is about avatars and their human counterparts. However, most of the photos are edited stills from the film, some are really not that great a quality.
Overall, its fine but I really expected a lot more from this book.
