Having been a big fan of DK guides, I was really looking forward to this volume, but unfortunately, I was to be disappointed. See, for whatever reason, somewhere along they line, they decided that this book should cover both live-action Transformers movies. This despite the "Revenge of the Fallen" logo, which implies a focus on the 2nd movie. As a result, this book ends up mostly dealing with characters who already got extensive coverage elsewhere. In fact, the book doesn't even cover a sequel character until 3/4 of the way through! Would these pages, often dealing with now-dead guys like Blackout, Frenzy, Jazz, and Barricade, have been better used covering say, Arcee, Soundwave, Scalpel or even Alice? I'll go out on a limb and say "Yes, someone who buys a book with a 'Revenge of the Fallen' subtitle probably would have preferred that." Oh wait, I see that "ROTF" might actually a be a logo, and not part of the official book title. Cute.
Having said that, if you don't have the previous DK guides that cover the first movie, or if you just ignore the "ROTF" logo/title, this book is quite nice, and does have the usual lovely visuals and the kind of encyclopedic information that dorks like me love. On those terms, this is actually an above-average guide book, particularly for the price. I guess I'm just frustrated by what feels like a bit of bait-and-switch.
