Query: Terrible!

I wish I had paid attention to the first reviewer rather than the two who gave this a decent rating, or read the excerpt at the other reviewer did and discovered bad errors.There is nothing in this book that hasn't been said before, it's a cheaply made book, and the author's personal remarks are often dramatically off the mark.Don't buy it. Whedon has already had an excellent guide of the first half of the episodes of Firefly published, with the second guide for the rest of the series run to be released soon.
