I think this book is a wonderful treasure for Disney fans. The pages feel like you're looking through an actual sketch book and it's great to see the different drawings for the characters. Of course, you won't get as in depth of a look per film/character as you would for a "making of" book, but you get a good a mount of stuff, ranging from Mickey Mouse, all the way to "Tangled."
It's a lovely book for a Disney fan looking for a great book. Like someone else said, the only flaw are that there are no notes of any kind, so you can't tell who did what when and things like that. Still, a five star book.
