I read it as an "Okay, it's been on the bestseller list for more than a year, and I want to be on that list someday, so take notes" experiment. I was sorta bummed, actually. Lame characters, hamfisted plot. Lots of ideas -- I can see people getting all into that -- but man, the way he introduces them. "Suddenly, the protagonist flashed back to a class he'd taught years ago, complete with exposition and dialogue, and then ended the flashback by saying, 'Not now, man, there's no time to get sidetracked!'" Uh-huh. When I'm being chased through the Louvre for a crime I didn't commit, I ALWAYS flash back to old courses I've taught, and then go through them for several pages' length with full narration.
The things that really bugged me, though, were when he cried "surprise!!!" after lying to us or when he built suspense by not telling us things that we should in fairness know. There were chapter endings like:
Hero stepped into the room and looked at the object sitting there.
"My God," he said. "This changes everything."
Love Interest followed him and looked at the object as well. "Is that what I think it is?"
"Yes," he said. "Yes, it is exactly what you think it is." He picked it up, cradling it in his hands. "I can't believe I've found it after all these years. The world will never be the same. This changes everything."
END CHAPTER!!!! SUSPENSE!!!!
'Cause, um, see, if we're IN his viewpoint, then we get to know what he knows, and see what he sees. I'm usually cool with a light bend of this rule -- the TV-show version, where the hero opens the door, and then you stay on the hero's face as he says "Oh my God..." and then we cut to commercial. But Brown does this "Haha, I'm not telling the reader" garbage for several paragraphs, and THEN cuts to another scene. It's clumsy.
And lying to the reader is just lame. When a big plot twist happens, I as the reader should either be saying, "Dude, wow, neat change" or "Oh, why didn't I see that coming?" I should NOT be saying, "Well, that felt like the author trying to yank me around," or "That violates every single bit of what passes for this person's character development thus far."
I suspect that many of these issues are strictly writer-issues, though. Just like I can't watch most movie fight scenes without grimacing, or my wife can't watch people in movies try to play musical instruments ("Oh, for crying out loud, Rolf the Dog had better finger position than that!")...
