Content-wise I was rather surprised by the variety of topics, ideas and concepts presented and sources quoted, although almost all were only brushed upon.
Still, the book is massive (540 pages, roughly 20x30x3.5 cm). Glad I got the hardcover, doubt the paperback would survive long.
The writing style I found rather (unintentionally) amusing (at times), though certainly not dry and a bit jumpy at times, though the common thread is always visible.
What put me off was the design;
Among the huge amount of pictures, far too many were tacky, trashy, tasteless, ridiculous and/or unnecessary (half a dozen pictures of LaVey shopping or boobs covered in blood would be good examples for the later) in my estimation.
The typesetting (and typography in some cases) is terrible and in general the placement of photos, illustrations and "boxes" containing commentaries or additional information are rather chaotic.
Certainly there are great illustrations and artful photos, though in some cases they are too small, despite the high quality print.
