Never really understood why these modern best-seller writers are so popular. It's not as if the text is even easy or enjoyable to read! At least with guys like Tom Clancy you got a load of military hardware stuff to get off on.
Believe it or not but a vast majority of readers have no interest drowning in materiel specs while reading a book.
Ridiculous, I know. I had the same reaction when someone recommended I read the abridged Moby Dick(without knowing I've read the unabridged thrice), because who wants to hear about all those random whale facts?
I don't remember it that way. I took it more more as being about the definition of "fish", and demonstrating that whalers don't think about things the same way that non-whalers do. It's not ignorance; he acknowledges repeatedly throughout that whales breathe air, and nurse their young, and other mammalian traits.
Never really understood why people like Tom Clancy, it's not as if it's enjoyable to read about a bunch of mililtary hardware. At least with Dan Brown you've got a load of interesting mysteries and locations to get off on.
(more seriously: I think both authors understand their markets and are savvy about delivering what they want, critics be damned)
