The setting and plot are really good (up until right near the end) but the characters are shit. I didn't like any of them and didn't care if they lived or died - which is problem when their survival is the entire basis for the story's stakes.

The other problem with the book is that it ends like a Marvel movie - with a big, dumb fight that means nothing. It's even got bosses with glowing weak points.

The good aspects of this book reminded me of the TV show From. Unfortunately the author felt the need to explain too much (especially towards the end) and the characters sucked. Watch From instead.
