So far this book is nowhere near as interesting as Pattern Recognition. If P.R. and Spook Country were sisters, wait, fuck that metaphor. A book like this is only as good as it's characters, and while Cayce Polland, the protagonist from P.R. has three competitors in Spook-y, none of them really stand up. Hollis Henry, the only female protagonist and some kind of Kim Gordon wannabe, especially pales in comparison to Cayce's hyper-anonymous, dreamlike strangeness.
It's pretty lame to criticize a book i haven't completed reading, but I already feel like I can understand the Tom Clancy comparisons, which really isn't a good thing.
It's strange, because this book was really well received... Gibson has a new book coming out on September 7th called Zero History, I'm hoping I'll like it a little better (although it looks like Hollis Henry is making a comeback...)
Note: I finished this a couple weeks ago (7/9/10). It becomes less boring (and maybe I forget more about P.R.) about halfway through the book. The conclusion was somewhat underwhelming, but overall fairly interesting post-cyberpunk-that's-not-actually-cyberpunk.
