The book itself is alright with good information on the transformers that are in it (height, weight in metric tons, information about armor, weapons, and parts, direct quotes from the movie made by the characters, etc). However, many transformers are excluded such as Starscream, Ironhide, and a few other Decepticons. Mind you, this book was written after the first movie came out and therefore doesn't have Sideswipe, Dino, Brains, Wheelie, the Twins, Devastator, The Fallen, Shockwave, or any of your other favorite characters that are in Revenge of the Fallen or Dark of the Moon (or in the newest movie "Age of Extinction" that we're all excited for).
If I were you, I'd buy "Transformers Revenge of the Fallen: The Movie Universe" by the same author instead of this.
Also, the person I bought this book from said that it was in very good condition. Apparently some people have different opinions on what "very good" means. When I got my book, there were library stickers all over it, all of the corners were badly damaged, the pages are ripped and crinkled and some even have food on them. The book sleeve is absent, and the front has scratches. It looks like it's been in a little kid's backpack for a few weeks. Just sayin' if you are going to buy this book, get a NEW one.
