It's of the Dan Brown School of writing.
Just don't subject yourself to it.
Okay, I'll justify the above by telling you that my main objection is that the novel is badly structured. Steig Larson (not sure I've spelled that right...) has tried to smush two stories into one. The beginning is overworked, full of detail about financial fraud which is difficult for lay persons to understand, and for most of the book nothing happens. The premise of the book sounds really interesting, with a really atmospheric and intriguing opening, but the ending isn't worth the time it takes to get there.
