Despite the credits this is primarily Jones' work, with all the new chapters his and much of the earlier portions apparently rewritten by him.
I have a love-hate relationship with this book. The extremely subjective quality of this work, from a very disillusioned comic writer makes this both entertaining and frustrating to read.
The book is heavily biased towards the Silver Age and heavily biased against anything that comes later, with the occasional exception. Among the exceptions of course are the author's own works, which tend to get more air time than they might get in other history books. The Trouble With Girls certainly deserves a comment or two, but not a page or so.
The book goes into great detail about Kirby. While these points may certainly be accurate, he mentions Kirby so often that I did find myself wishing he would find something else to talk about occasionally, or perhaps write a separate book about Kirby. This is by no means a slight against the King, but it's nice to also talk about other creators in their own right.
Very well illustrated, with some interesting behind the scenes commentary (often unfortunately to the point of gossip and innuendos which doesn't always have much to do with a creator's abilities). But the bitterness does make the book a bit of a struggle. Which is a shame because it's often a very engaging read.
