Firefly Official Companion - Volume 1
What we wanted was production notes and other background material fleshing out the Firefly universe - politics, technology, culture, geography - and notes from the production staff about their inspirations for the sets, spaceships and costumes.
What we get is a handful of interviews covering the same self-congratulating tripe from the luvvies as published in every TV guide and DVD extra, and a number of scripts printed out in full. Since this book is not called “Firefly - The Scripts for the first half of the episodes, and 5 pages of reprinted filler”, I suggest you avoid.
Incidentally, the recently released Volume Two is just as bad.
