Being a Trekkie, I just enjoyed EVERYTHING about the Compendium! It is a season by season, episode by episode account of the entire Original Series for Star Trek. Pictures of the actors on the set, tidbits about actors and scenes abound for those who like to know the behind the scenes stuff. ("What actor has played both a Romulan and a Vulcan?" type of trivia)If you don't like Star Trek? Don't bother, this book will bore you. Love TOS? Then you'll enjoy this greatly!
