While I liked this book, it didn't really match up to my expectations from the earlier books in the series. That said, the character of Johnson and his, slight, character arc throughout the book are well done. I do wish there was more time spent on honest character development, but that said this is the literary equivalent of a stereotypical action movie, and there is nothing wrong with that! despite my rating, I did enjoy it. I just wish there was a bit... more to it.
