Content wise, it's good. It has interviews (more like a round table), character guides (including all the animal characters and even some insects), and art work used in both the manga and the anime. It's pretty much packed with stuff.
And that's its weakness as well. The book isn't particularly large, and it's only 120 pages, so things tend to be be printed in small sizes. Otherwise, they wouldn't all fit. In the end, though, it's priced accordingly (relatively cheap), so there's no problem with its value. I wouldn't have minded paying a little more for a larger print, though.
