To borrow a familiar word: Fascinating. An _incredibly_ in-depth and copiously researched look into the creation and production of the original series. The sole problem is that it seems it could have used another editing pass or two, with numerous spelling or formatting errors, and occasional odd errors when venturing beyond the boundaries of the original series (the differing looks of Klingons over the years was not explained during _The Next Generation_, nor was it due to there being "different species" of Klingons). Still, even with that minor gripe, the amount of detail contained in this textbook-like tome, much of it sourced from original production documents given to the author by Gene Roddenberry himself in the 1980s, is wonderful for the die-hard fan. Looking forward to the coming volumes two and three, covering seasons two and three, respectively.
