The tone is like hearing someone who lived a portion of literary history tell you his favorite parts-if he does not tell it very well and you cannot ask questions. That is the glory and frustration of this book. Ackerman was around early enough to make-up the term “sci-fi,” was agent for dozens of writers, read the sci-fi pulps from the very first, watched the different trends in film and TV, but in telling about his favorite authors, books, stories, films, and TV shows, he seldom gives a sense of why he includes one instead of another, and just as bad, he virtually omits radio sci-fi altogether. Most of the others get their own chapter. Time and again I wished this were a conversation so I could ask why a writer was so interesting to him, because time and again he does not say. What is there can be enjoyable to read and many of the illustrations are wonderful, but the book is basically a failure. That it receives a generous three stars is testimony to how readable it is and how fascinating many of the illustrations are.
