I'm not going to review the actual content of this book. There are lots of other reviews out there in which you can learn about this great comic book series.
What you really want to know is: should I shell out for this or not?
If you are familiar with the paperback "Compendium" editions from Top Cow, this is exactly like those, except hardcover. That's a major improvement, as those compendium paperbacks were easily damaged. It is very thick, unlike the item displayed in the picture. The image content fills the pages: unlike Marvel Omnibuses or hardcovers, there are no borders at all. Also unlike the Marvel books, the paper is rather flimsy and thin, although glossy with good reproduction quality. In fact, the pages seem thinner than standard comic book paper used by most independent comic book publishers. The page size is exactly the same as standard comic book pages.
The reason to buy this book is to get all this content in one place, and there is a ton of that. They aren't kidding when they list 1000 pages. But other than that the book design isn't much. Unlike competing oversize editions published by DC, Dark Horse, or Image, these Compendiums are the size of standard comic books. That's a real let down for fans and a missed opportunity for the publisher.
Without borders around the artwork, some of it gets lost in the massive spine fold. The weight of the book makes it unwieldy, and easy to lose your grip on-- so the flimsy pages become a real liability--easy to damage as you fumble with the book in your lap. They also feel like they might tear if you turn the pages with any strength.
I am quite happy with this despite those complaints, as I didn't have any of this material in another format. For those who do have other versions of these issues, collected or otherwise, there's not much motivation to buy this, as it really is just a bunch of standard comics bound into a thick and heavy tome.
